People overestimate progress in physical world. 2035: robot population will soon be larger than the human one

I'd bet that in most places 9 years is about the time needed to build a residential building. I think a good way to think about this is to think of this as producing a serial car. From pitching and capital acquisition to building a prototype to software, regulatory and then the final product which needs multiple factories and supply chains. Yes, of course robots sound cooler and there are compounding effects yada yada, but on the other side there are as many obstacles as things that accelerate this product (like capital acquisition and fearmongering of gov to bend regulatory stuff faster).
