Despite the passion for V6 engines and the characteristic sound of combustion vehicles, physics demonstrates the superiority of electric cars due to their remarkable efficiency. Electrified vehicles have become more attractive, presenting lower operational costs per kilometer traveled, more accessible maintenance, reduced emissions, silent operation, and exceptional torque.
Batteries are evolving, becoming lighter, offering greater autonomy, and decreasing in cost, largely thanks to Chinese production. Although some advocate for maintaining the internal combustion engine in luxury sports cars, such as those made by Ferrari, Porsche, or Aston Martin, the electric vehicle is not behind in terms of performance, delivering torque equal to or superior to traditional engines.
However, the author argues that the main focus should not just be on performance, but on efficiency. The inefficiency of the internal combustion engine is glaring: it wastes between 60% and 70% of the energy contained in the fuel through friction and heat, in addition to generating environmental pollution.
In contrast, the electric motor manages to deliver between 90% and 95% of the energy it receives to the wheels. While current Otto or Diesel engines convert only 30% to 40% of the chemical energy from the tank into mechanical energy, the difference is substantial. Furthermore, Chinese companies, such as BYD and Dongfeng, are achieving efficiencies in gasoline engines considered unattainable, with 46% and 48%, respectively.
Although there are barriers to the total adoption of electric vehicles, such as battery cost and weight, temperature sensitivity, and charging points, these difficulties are being overcome rapidly. The author points out that the third phase of electric vehicles began just over ten years ago, but the first models circulated in the late 19th century, even before gasoline cars.
The electric vehicle only lost the competition to liquid fuel due to battery range limitations, a problem that persists today. Historically, women rejected the arrival of the gasoline car because they lacked the strength to operate the engine with a hand crank and disliked the smell of exhaust. Despite taking almost 150 years to consolidate, the electric vehicle became irreversible, mainly due to its incomparable thermal efficiency.
Artificial intelligence embedded in smartphones attracted significant attention during the World AI Conference held in Shanghai. As reported by AFP in TechXplore, manufacturers presented devices capable of performing tasks via voice command without the user needing to launch multiple applications.
At least three manufacturers demonstrated models equipped with AI agents at the event. The core idea is to transform the smartphone into an autonomous assistant that can independently handle tasks such as price comparison, travel planning, video editing, or ordering food.
Among the new offerings was the NaviX Ultra from Nubia, which is integrated with Doubao chatbot developed by ByteDance, the owner of TikTok. Announcing the device, the company stated: 'A new era of AI agent smartphones is beginning.'
The concept is not entirely new; a prototype called 'Doubao Phone' previously demonstrated similar integration, but its functionality was partially limited after major platforms restricted the assistant's access.
The demonstrations included capabilities such as ordering food by voice, comparing prices across different stores, organizing trips and purchases, as well as video editing and productivity task support.
However, it turned out that the main obstacle is not the artificial intelligence itself, but the issue of integration with applications and services of competing companies, which are not always willing to grant such access.
Kiranjit Kaur, an associated research director at IDC, explains this by saying that platforms seek to maintain direct contact with their users, fearing 'loss of control to another company.'
The expert also notes that the industry is still searching for a truly effective model, stating: 'AI agents are everyone's dream, but we have not reached it yet,' emphasizing that such solutions currently have shortcomings in various scenarios.
According to Chinese specialized publications cited in the article, the NaviX Ultra aims to work in partnership with applications, avoiding unauthorized system access.
Other companies are also betting on this direction. Honor introduced the 'Robot Phone,' which features a camera mounted on a small robotic manipulator capable of recognizing gestures, accompanying music, taking selfies, and stabilizing video.
Startup StepFun showcased the STEPX Neo, integrated with services like Alipay and Didi, to combine functions of shopping, travel, productivity, and video editing.
Besides China, Google and Brain Technologies are also increasing their investments in AI smartphones.
Mark Einstein, an analyst at Counterpoint Research, believes there is no clear winner in this competition yet. He predicts that within the next five to ten years, the interaction between users and smartphones could change drastically, reducing dependence on traditional applications and paving the way for increasingly common AI assistants in daily life.

Samsung implemented job cuts in its electronics operations in the United States, a move that occurred during the relocation process of Samsung Electronics America's headquarters to Texas. The impacts mainly affected employees located in New Jersey and Texas itself.
According to Reuters, 739 positions were affected in Englewood Cliffs, New Jersey, and about 100 workers from the unit in Plano, Texas, also lost their jobs. Samsung communicated that some employees received offers to accompany the transition to Texas, but others had their contracts terminated. The company did not disclose the exact number of acceptances or the total number of layoffs.
The operation in question is Samsung Electronics America (SEA), which manages consumer electronics areas, covering mobile phones, televisions, and home appliances. It is important to note that this division does not include the company's chip-related businesses.
The cuts in Plano, Texas, affected approximately 100 professionals, including members of the mobile team, as reported by a source close to the matter consulted by Reuters. Documents analyzed by the agency indicate that some employees were notified on June 30th about a 'workforce reduction across the company,' warning of a considerable impact.
Furthermore, posts on LinkedIn showed that more than 30 employees, covering sales and marketing roles in New Jersey, Texas, and other parts of the US, reported recent layoffs or departures.
This decrease in vacancies occurs amid internal contrasts at Samsung. While the semiconductor division is expanding due to high demand for artificial intelligence, consumer-facing products face greater competitive pressure. The South Korean manufacturer forecasts a 19-fold growth in profit in the second quarter, driven by the AI chip market, and announced plans to invest hundreds of billions of dollars in new semiconductor factories the previous month.
In the mobile phone segment, competition with Apple remains fierce. In the television and home appliance markets, Chinese brands such as TCL and Hisense are intensifying competition. Factors pressuring consumer businesses include the rising cost of chips driven by AI advancements, intense competition in the smartphone market, Asian competition in TVs and home appliances, and the redirection of investments toward AI infrastructure.
Samsung stated that the headquarters move may lead to adjustments in the composition of the workforce, particularly for those who cannot move or in sectors requiring reorganization. The transfer of Samsung Electronics America's headquarters follows a trend observed in technology companies expanding their operations in Texas, attracted by lower tax benefits and more favorable business regulations.
The state already has Samsung chip facilities and a mobile operations center in Plano. The company justified that the move aims to 'strengthen collaboration and optimize organization by bringing more teams together within a growing ecosystem of technology and artificial intelligence.' Despite these adjustments, Samsung assured that there is currently no broad global restructuring in its consumer product line.
Additionally, Reuters reported that Samsung SDS America notified possible cuts of 179 positions in Ridgefield Park, New Jersey. The company itself clarified that such changes are linked to the relocation of the division's North American headquarters and do not constitute general layoffs or restructurings.
