Exactly this. If they had been innovating in vacuum technology then maybe this article would have a point. But they were building stuff for the military and for space, and there's a good reason investors wanted them to get out of that because it was sucking up money and not resulting in better vacuum cleaners.
Well it's 2025, we've just spent the better half of the year discussing the bitter lesson. It seems clear solving more general problem is key to innovation.
Hardware is not like software. A general purpose humanoid cleaning robot will be superior to a robot vacuum but it will always cost an order of magnitude more. This is different from software where the cost exponentially decreases and you can do the computer in the cloud.
I'm not sure advancements in AI and advancements in vacuum cleaners are at similar stages in terms of R&D. I'd be very wary of trying to apply lessons from one to the other.
