A new wearable from an MIT spinout allows users to communicate silently with AI and other devices. The technology interprets neuromuscular signals from the jaw and face, representing a significant shift in how we interact with digital systems.

This moves beyond traditional inputs like keyboards and voice, potentially creating a more seamless link between human thought and computers. But what are the broader implications for personal computing and accessibility if we can control our devices just by thinking?

Today in AI:

  • MIT's wearable AI reads silent speech

  • OpenAI's plan to fix AI hallucinations

  • Cognition AI's new $10.2B valuation

What’s new? An MIT spinout, Alterego, demonstrated a new wearable that interprets neuromuscular signals, allowing users to silently communicate with AI and control devices just by thinking.

What matters?

  • The device interprets neuromuscular signals from the jaw and face, enabling it to understand words you articulate internally without making a sound.

  • Users can silently type, search, and control applications, as shown in a demo where it was used for taking notes and communicating with an AI.

  • Beyond productivity, the technology offers profound accessibility applications, providing a voice for people with speaking conditions like ALS.

Why it matters?

This technology moves human-computer interaction beyond keyboards and voice commands into the realm of silent, internal thought. It represents a significant step toward seamless integration between human cognition and digital systems, with major implications for accessibility and personal computing.

What’s new? OpenAI published new research that identifies why models confidently invent facts. The team proposes changing how models are evaluated to encourage admitting uncertainty over making things up.

What matters?

  • The problem isn't that models lack intelligence, but that they are rewarded for guessing on benchmarks, which incentivizes them to bluff rather than say "I don't know."

  • OpenAI's proposed solution is to adjust the evaluation process to penalize incorrect answers and give credit for appropriate uncertainty, which shifts the incentive toward truthfulness.

  • This change could produce AI assistants that are significantly more reliable for fact-based tasks, as they would learn to differentiate what they know from what they are guessing.

Why it matters?

This new approach could significantly improve AI's trustworthiness and make models more dependable for professional applications. An AI that knows what it doesn't know is a major step toward building truly helpful and safe systems.

How 433 Investors Unlocked 400X Return Potential

Institutional investors back startups to unlock outsized returns. Regular investors have to wait. But not anymore. Thanks to regulatory updates, some companies are doing things differently.

Take Revolut. In 2016, 433 regular people invested an average of $2,730. Today? They got a 400X buyout offer from the company, as Revolut’s valuation increased 89,900% in the same timeframe.

Founded by a former Zillow exec, Pacaso’s co-ownership tech reshapes the $1.3T vacation home market. They’ve earned $110M+ in gross profit to date, including 41% YoY growth in 2024 alone. They even reserved the Nasdaq ticker PCSO.

The same institutional investors behind Uber, Venmo, and eBay backed Pacaso. And you can join them. But not for long. Pacaso’s investment opportunity ends September 18.

What’s new? Cognition, the startup behind the AI software engineer Devin, just raised $400 million, pushing its valuation to a massive $10.2 billion. This funding underscores the huge investor bet on AI agents that can automate complex work.

What matters?

  • The company’s revenue has rocketed from $1M to $73M in just nine months, demonstrating rapid market adoption.

  • The new funding round was led by Founders Fund, signaling strong confidence from top-tier venture capitalists in the autonomous AI space.

  • This valuation follows Cognition's recent acquisition of rival AI coding platform Windsurf, consolidating its position in the market.

Why it matters?

Cognition's decacorn status solidifies the AI agent sector as a major focus for venture capital. This intense investment accelerates the push for AI that can independently manage and complete complex professional tasks.
