Forget singularity, do you think the robotics problem is genuinely hard enough that if we devoted significant amount of intelligence to it, it would not get solved?

>any day now Optimus will become sentient and replace home builders.

I think you're kidding about being "sentient" but it feels like they just have to get somewhat good at a very few tasks and we would be able to automate some large swath of manual labour. We don't need that many fancy tricks to get there. A lot of people are already reporting significant speed ups in Bio research, why wouldn't we see that in robotics?
