Logitech’s MX Master 4 Is Still the Best Productivity Mouse

The loss of soft-touch plastics may seem like a downgrade at first, but I vastly prefer uncoated plastics for long-term use: My MX Master 2S developed unsightly smooth spots on both mouse buttons where the soft-touch coating wore down, and other long-term users have reported the coatings becoming tacky over time.

The two primary mouse buttons and the scroll wheel are nearly dead-silent. Despite this, they still have clear feedback with a distinct bump and no mushy feeling. In the ratcheting mode, the mouse wheel has a noticeable bump between each scroll. In the smooth mode, the wheel has just enough resistance to be controlled easily, while still spinning freely.
The horizontal scroll wheel on the side permanently scrolls smoothly and has significantly more resistance than the primary scroll wheel. This allows for greater control of the wheel and helps protect against accidental scrolling when moving your thumb. Scrolling is incredibly smooth, without any catching or scratchiness, and the ridged texture of the aluminum wheel feels comfortable and easy to manipulate. Clicking the wheel is still fairly loud, like any mouse. The three side buttons and the top button have a muted click, and it’s not disruptive.
Despite weighing 150 grams, this mouse is easy to glide around a surface. The feet are smooth, sliding easily while still having enough friction for precise control, and the sculpted shape makes it easy to move and lift. While the high weight means it won’t be ideal for competitive, high-intensity gaming, the shape is preferable for longer sessions, whether you’re grinding out dungeons or slogging through spreadsheets.
The sensor is capable of up to 8,000 dots per inch, but most people will likely leave the sensitivity well below that. I didn’t have any issues with input registration, skipping, or shaking, and the sensor felt incredibly precise on all surfaces, even frosted and transparent glass.
Gesture Controls and Haptics

The MX Master 4’s gesture controls are one of its most prominent features. These have been featured on every generation of the MX Master line, with only small changes across generations. The gesture control button was previously located on the bottom of the thumb rest, hidden underneath the rubber surface, but has now been moved to a standard button on the side, which I found more comfortable and natural to use.

EPA, Energy, Interior announce plans to support coal mining

On Sept. 29, the Trump administration announced a series of actions intended to boost coal mining and electricity generation, its latest move in a government-wide effort to reverse the fuel’s decline.
The announcements from the EPA, Energy and Interior departments are intended to bolster the domestic coal industry at a time of increasing electricity demand due in large part to artificial intelligence data centers. Administration officials and congressional Republicans said these changes are necessary to ensure U.S. competitiveness.
“Around the world, coal is still growing. People talk about peak coal, most consumption, but last year was the year that the most coal was used in the world, and of course we’re in a competition,” Interior Secretary Doug Burgum said, referring to the AI industry in China. “If we don’t lead in electrical production, we’re going to lose the AI arms race.”
The Energy Department will provide $625 million to subsidize and support coal-fired plants, including $350 million for retrofitting and recommissioning coal plants at or near their retirement dates and $175 million for coal power projects in rural communities.
The Interior Department said it will open more than 13 million acres of federal land for coal mining and streamline permitting the approval process for other mines. It will also implement a provision of the Republican reconciliation law that reduces the royalty rate for coal from 12.5 percent to 7%.
And the EPA announced regulatory changes that would favor coal-fired power plants. They include providing plants with more time to comply with existing effluent limitations guidelines, which govern coal ash wastewater pollution, and an advance notice of proposed rulemaking on changes to the Clean Air Act’s regional haze rule.
U.S. production of coal has declined for more than two decades across Republican and Democratic administrations, with this most carbon emissions-intensive fuel displaced by natural gas, wind and solar power.
However, the Trump administration has been critical of wind and solar energy, blocking projects on federal lands and waters. Officials argue these forms of energy, even when paired with batteries, remain too unreliable and cannot support AI and other industries. In addition, Energy Secretary Chris Wright and others have criticized wind and solar power subsidies, arguing they are evidence these renewables are not cost-effective.
Instead, they have called for increased efforts to preserve and expand forms of baseload power, including coal. Earlier in 2025, President Donald Trump signed an executive order to support the coal industry.
When addressing the United Nations, Trump reiterated his belief that climate change was a “hoax” and said European nations were on the “brink of destruction because of the green energy agenda.”
EPA Administrator Lee Zeldin said in a Sept. 25 Fox News interview that he agreed with Trump’s statements. Also last week, Wright characterized a network of scientists who agree about the severity of climate change and its impact as “activists.”

California enacts AI safety law targeting tech giants

California Governor Gavin Newsom has signed into law groundbreaking legislation requiring the world’s largest artificial intelligence companies to publicly disclose their safety protocols and report critical incidents, state lawmakers announced Monday.
Senate Bill 53 marks California’s most significant move yet to regulate Silicon Valley’s rapidly advancing AI industry while also maintaining its position as a global tech hub.
“With a technology as transformative as AI, we have a responsibility to support that innovation while putting in place commonsense guardrails,” State Senator Scott Wiener, the bill’s sponsor, said in a statement.
The new law represents a successful second attempt by Wiener to establish AI safety regulations after Newsom vetoed his previous bill, SB 1047, after furious pushback from the tech industry.
It also comes after a failed attempt by the Trump administration to prevent states from enacting AI regulations, under the argument that they would create regulatory chaos and slow US-made innovation in a race with China.
The new law says major AI companies have to publicly disclose their safety and security protocols in redacted form to protect intellectual property.
They must also report critical safety incidents—including model-enabled weapons threats, major cyber-attacks, or loss of model control—within 15 days to state officials.
The legislation also establishes whistleblower protections for employees who reveal evidence of dangers or violations.
According to Wiener, California’s approach differs from the European Union’s landmark AI Act, which requires private disclosures to government agencies.
SB 53, meanwhile, mandates public disclosure to ensure greater accountability.
In what advocates describe as a world-first provision, the law requires companies to report instances where AI systems engage in dangerous deceptive behavior during testing.
For example, if an AI system lies about the effectiveness of controls designed to prevent it from assisting in bioweapon construction, developers must disclose the incident if it materially increases catastrophic harm risks.
The working group behind the law was led by prominent experts including Stanford University’s Fei-Fei Li, known as the “godmother of AI.”
