No insights or opinions to contribute. Just thanks for keeping across all of this, so that I at least have a broad idea of what's going on.

This seems necessary, since I'm genuinely embarrassed by the opinions I held on the matter as recently as February.

> What’s striking about the above is that the alarms are simply ‘oh, we solved robotics.’

Just to clarify, I wasn't really describing smoke alarms, but rather the sort of "alarms" used by fire companies when you already have a major fire underway. According to Wikipedia, a 3-alarm fire would involve calling out 12 engine companies and 7 ladder companies. It's not an early warning tool, it's a crisis management tool. I am not trying to tell people when they should start looking for EXIT signs and walking calmly in that direction. GPT 4 is already at that point. Please move towards the EXIT signs now. I'm trying to tell people, "If you see X, you need to be prepared to mount a major, immediate response with significant resources, or else the city will burn."

I think that it's worth having this kind of alarm, too. Especially for people who aren't sold on ultra-short timelines where an AI quickly bootstraps itself to effective godhood and disassembles the planet with nanobots. If an AI is forced to rely on some combination of humans, robotics and synthetic biology to manufacture GPUs, then we need to be able to distinguish between different sizes of "fires." You need different responses for "there is a grease fire in my wok" and "we have multiple high-rises on fire" and "the western US is on fire again."

Anyway, more on robotics...

The problem with robotics is pretty much like the problem of self-driving. The first 90% is 90% of the work. The next 9% is _another_ 90% of the work. And the next 0.9%... You get the idea. And to complete most real-world tasks, you'll need a lot of 9s. Waymo has mostly solved self-driving, but "mostly" isn't nearly good enough.

We've been able to build "pretty good" robots for a couple of decades now. I'm not talking your classic factory robots, which are incredibly inflexible. I'm not even talking about pick-and-place robots, which involve visual processing and manual dexterity: https://www.youtube.com/watch?v=RKJEwHfXs4Q. We've actually had jogging robots and somersaulting robots and soccer robots for a while now. And they're not terrible? Many of them are similar to self-driving cars: They can accomplish a specific task 90-99.9% of the time under reasonably real-world conditions. Which isn't close to good enough to make them viable.

This is a major reason why a working "handybot" is one of my alarms that we're nearing the endgame. If you've ever worked on old houses, you'll know that nothing ever goes quite according to plan. You need vision and and touch and planning and problem recognition and fine manipulation and brute force. A hostile or indifferent AI which can solve this is almost certainly capable of surviving without humanity, given enough time to build out a full-scale industrial economy.
