The Download：人形机器人的 AI 路线之争与便携橡胶水坝

The hype around humanoid robots is reaching fever pitch. Much of it comes from the idea that the same AI advances behind ChatGPT and Claude could enable robots to imitate human movement the way chatbots imitate human language. But many researchers are skeptical.

They argue that such assumptions minimize the challenges of using an intelligence built on language and images to master the infinite variability of the physical world. They also point out that conflating humanoids with so-called generalist machines is misleading.

Across robotics labs, tensions have emerged over whether current forms of AI are all that’s needed to perfect all-purpose humanoids or whether an entirely new path is required.

As sea levels rise and flood risks worsen, WaveSave has emerged with an ingeniously simple tool: a portable rubber dam that’s quick to install when flooding starts.

Anyone can unfurl the SlamDam on the ground along a riverbank or shoreline and pump it full of water until it swells into place. And there it stands, up to 1.3 meters high, shielding nearby property or structures from damage as waters rise.

WaveSave now plans to take its unusual approach to flood protection much further .

Our Climate Tech Companies to Watch list is always a little ray of hope for me—there are some fascinating ideas out there about how we power our world or move away from fossil fuels.

Our chosen companies also reflect several aspects of the current moment. One is that China is the center of the climate and energy tech world. Another is that everybody wants a piece of the data center pie. And then there’s the fact that the grid needs support, with energy storage a key piece moving forward.

Here’s what this year’s list reveals about the state of climate tech .

Quote of the day

—David Robinson, who last week quit his job as OpenAI safety transparency lead, tells The New York Times that his former company has built models that develop capabilities their creators did not explicitly design.

One more thing

The US government is organizing itself for the next era of computing. Ultimately, it has one big choice to make: adopt a conservative strategy that aims to preserve its lead for the next five years—or orient itself toward genuine computing moonshots.

There is no shortage of candidates, including quantum computing, neuromorphic computing and reversible computing. And there are plenty of novel materials and devices. These possibilities could even be combined to form hybrid computing systems.

We can still have nice things

A place for comfort, fun, and distraction to brighten up your day. (Got any ideas? Drop me a line .)

+ An experimental pair of contact lenses can repair themselves with UV light . + Meet Rich, the rescued squirrel who visits the woman who saved him every day . + Reminisce about the lost joy of music piracy with this wistful reflection on a time before streaming. + What would rainbows look like on Tatooine? Randall Munroe, a former NASA roboticist, has the answer .
