Ten years ago, we were afraid of fast charging. The 10,000mAh batteries are going the same way

The world of smartphones is divided in two: a Chinese market betting on gigantic silicon-carbon and some “traditional” manufacturers who do not dare to take the leap. This weekend, the controversy was sparked by YouTuber Marques Brownlee, after publishing a video that has surpassed one million views in less than 24 hours. what has happened. “The problem with smartphone batteries”is the title of a video that has spread like wildfire among the community tech. In it, he explained some of the problems that silicon-carbon batteries supposedly suffer from, a technology that China is betting on to boost the capacity of its phones. above 10,000mAh. The problems. Silicon-carbon batteries are not a new technology, but they have been starting to be implemented in smartphones for just two years. During this time, there are several concerns on the table. Possible swelling due to the expansion of silicon: with each charge, a battery contracts and expands. Silicon can triple its volume, generating greater internal stresses in the battery. At the same time, there are fears that this expansion-contraction cycle could cause cracks and leaks in the battery. Need for reinforcement in battery compartment (such as small steel cages) to contain swelling. Long-term reliability not yet demonstrated in smartphones. Yes, but. Concerns about whether silicon-carbon batteries are safe or not are legitimate. Just as, back in the day, we were worried that a mobile phone with “fast” charging like the OnePlus 3 in 2016 (those times when Dash Charge was 30W) could explode. Today there are already mobile phones with 120W. The first commercial mobile phone to incorporate this type of battery was the Honor Magic 5 Pro in its Chinese version. No cases of the slightest problem have been reported to date in its more than two years of life. Manufacturers do not go crazy. Manufacturers are more than aware of the possible dangers that these types of batteries can have, and equip their phones with specific chips to control the charge in real time if excess heat is detected. Some brands, like Honor, go so far as to create microscopic tunnels in their batteries so that lithium ions can reduce chemical friction. Because yes, although carbon silicon batteries are called that, they are not made of pure silicon, they are a natural evolution of lithium batteries themselves. It’s not that easy. The next challenge after the introduction of silicon-carbon batteries has been to take advantage of their ability to store greater energy in a smaller size to achieve barbaric capacities: 7,000mAh, 7,500mAh, 10,000mAh. Energy densities notably higher than those that large manufacturers, such as Samsung, Apple and Google, currently mount in their high-end phones. Here an extra degree is added to the uncertainty: not only do we have more modern and not so tested batteries, but we also have capabilities that make their behavior even more unpredictable. Go deeper. The war for high-capacity batteries adds, apart from doubts about their reliability on the part of some manufacturers, logistical and economic challenges. They are more expensive batteries, and some manufacturers They are not taking them out of China yet. for that same reason. Added to this is that although the spec sheet tells us about milliamp hours, the main measure to determine the energy capacity of a battery is watt hours (Whr). Europe does not like batteries with more than 20 Whr, and they require longer and more expensive transport and authorization protocols. If the RAM crisis threatens to skyrocket the price of smartphones, thinking about incorporating significantly more expensive batteries does not seem like a viable plan to maintain the current margins of large manufacturers.

The Ukrainian army that is not afraid of Russia. They arrive as outdated machines and become robots for war

The year 2025 has been a radical change in the Ukraine War. We had seen drones with shotguns of double cannonrobots Lanzaluelaunmanned vessels With missilesairplanes With shotguns or even devices with kilometer cables of optical fiber Looking for its goal through algorithms. However, in recent months a change in trend has been accelerated. Because soldiers are no longer recruited, they are recruited directly robots. Even if they are antiques. Improvising on the front line. It Forbes counted. In an abandoned Soviet warehouse in Donetsk, Ukrainian soldiers and engineers transform old vehicles into non -manned combat systems, the called UGV. Under the command of Oleksandr, head of the Robotic Unit of the Antares Battalion, the workshops work thanks to raffles, donations and volunteer networks that Finish pieces and spare parts. Robots arrive with analog communications vulnerable to Russian electronic war and are completely comforted: new chassis, digital systems, StarlinkLte or encrypted links. Each conversion costs Between 750 and 1,000 dollarswithout counting satellite equipment, and requires maintenance after each mission. Once ready, the UGV are mostly destined for tasks logistics and evacuationtransporting ammunition, food or injured under enemy fire, although some are equipped with turretsmortars or electronic war modules. The speed remains limited and unstable connectivity, which forces them to use them mainly at night or in discretion conditions to avoid Russian kamikaze drones. Robots against the death zone. The proliferation of drones in Ukraine has extended The Russian “Kill” More than 15 kilometers behind the front line, causing entering or leaving positions to be one of the most lethal maneuvers. In fact, up to a 80% of the casualties Russians are already attributed to unmanned systems, and losses of Ukrainian logistics vehicles have forced multiply the use of UGVS for supplies and evacuations. The need is so high that in December 2024 the first compound Ukrainian assault was documented entirely by robotsand in July 2025 the 3rd Assault Brigade achieved an operation with Russian surrender Without own casualties. However, the UGV follow being vulnerable: day they are easy prey of FPV drones, and any signal failure can leave a wounded in the open field. Given this, some units are used as suicidal vehicles, launched against trenches, bridges or mined fields to detonate loads and open path. Another UGV development An accelerated race. Both kyiv and Moscow They experience With fleets of terrestrial robots, aware that the future of combat will depend on the mass integration of autonomous systems. Ukraine aspires to deploy 15,000 UGV By the end of 2025, supported by The Brave1 programwhile Russia shows prototypes With thermobáric launchers in their state media. The analysts They point That kyiv maintains advantage thanks to a decentralized network of start-ups and creative brigades, while Russia still depends on fragmented and volunteer efforts. At the same time, other global actors Like China They observe carefully the Ukrainian innovations to incorporate them into their own war doctrines. The test terrain in Donbás is accelerating a cycle of military innovation that in peace times would have been. Of logistics to direct fire. Ukrainian brigades already work for prototypes that They go further of the simple delivery of supplies: anti -aircraft turrets, UGVs kamikaze with Starlink to attack tanks, and modular platforms that can be adapted according to the mission. The main challenge is to reduce costs and simplify the operation to massify its deployment. The 28th mechanized brigade even presented a UGV equipped with A manpads Iglacapable of folding drones or low -level helicopters keeping operators covered. The vision is clear: an army in which the machines do the most dangerous work and the soldiers are preserved for control and supervision missions. The role of civil innovation. The rapid evolution of this robotic war It would not be possible without the direct intervention of Civil engineers and entrepreneurswhich have created a unique ecosystem of warlike innovation. Organizations as dignitas Ukraine They drive the Victory Robots programThey train soldiers in the management of UGVs and spread best practices among brigades. These initiatives They seek to build a “technological shield” that reduces human casualties and accelerates the adoption of autonomous systems. The next phase, they anticipate, will be the integration of artificial intelligence into terrestrial robots, multiplying their autonomy and efficiency in the battlefield. A robotic army. The Ukrainian bet for the UGV is not conjunctural, but part of a long -term strategy to compensate for demographic inferiority against Russia. If they manage to industrialize their production and stabilize the supply chain, these robots could become In spine From a hybrid army in which humans and machines fight side by side. Thus, the perspective of a future where entire brigades are accompanied by swarms of aerial drones and autonomous land vehicles no longer belong to science fiction, but to everyday reality of the Ukrainian front. For kyiv, robotics is more than a tool: it is the key to resist for years in a wear war and, perhaps, to define what the wars of the 21st century will be.

Working in Google, goal or Apple was the great dream of the newly graduated. Now they are afraid of them

According to A study The National Society of High School Scholars (NSHSS), in 2015 Google was the company in which millennials wanted to work as soon as they finish studying. Ten years later the situation It has changed remarkably. A few years ago, getting a job in any of the Big Tech was a pride. Not so much today. What happened. A new study of the NSHSS of reveals how a notable number of graduates no longer have large technology as the first options to seek employment. Working on them is no longer a dream, and their last movements make them rather a threat. Source: NSHSS. Big Tech don’t interest so much. In that study of 2015 Google was first among the companies desired by the newly graduated, while Apple was the 4th, Microsoft the 7th and Amazon La 11ª. In 2024 Google has passed to the 7th position, Amazon to the 8th, Apple at the 9th and Microsoft to the 16th. The interest in signing for these companies has been significantly reduced, and in the first six positions four hospitals, the FBI and NASA are now listed. Not to mention Spotify. The company Directed by Daniel EKwhich in 2022 was the third preferred by the newly graduated, is now in position 26, but there are other great displaced. Spacex has gone from position 9 to 22, Tesla from 15 to 33 and Airbnb from 27 to 49, for example. The threat of AI. In the study they point to clear reasons. One of them is that of fear of growing automation: artificial intelligence raises a remarkable impact for those positions that were previously covered by graduate young people. The same industry that previously promised innovation and a career with constant learning is now wrapped in frequent cases of sudden mass layoffs. Companies releasing ballast. The advance of AI both in Big Tech and other companies has allowed to validate the idea of trying to do more. Microsoft is in records of benefits and also dismissalfor example, but other important technological ones Like Amazon They have frozen their hiring while Google has opened the door so that employees who are not happy with the company abandon it freely. Volatility in these large companies is huge. The objectives change. Salary and prestige matter between millennials and gene Z, but according to a Network Trends survey cited In The Times of India, 76 & students put as great priority work stability above those metrics or even location. In fact, there seems to be a turn with a clear social purpose, such as those related to medical institutions. Doubts about whether or not to go to university. Another study Made by Deloitte It reveals how another of the foci of these generations is to continue learning, but not necessarily in academic environments. 31% of the Z Z and 32% of the millennials who participated in the survey indicated that they had decided not to go to universityespecially for the high cost of these institutions and for skepticism about whether that investment ends up being profitable. Changes in labor scene. The technological sector is especially irregular. Mass layoffs contrast with that new phenomenon of the AI Super. What a goal is hiring for hundreds of millions of dollarsFor example. The talent migration in the AI segment – with the money in between – contrasts with the questions that many recent graduates are asked now: what is the ethical impact of my work? Will it continue to exist within five years? There is a redefinition of ambition and the purpose of work itself. Not only should it be profitable, but also have a clear purpose behind.
