That is why I stated transistor improvements what was previously known as Moore's law will continue for at least another 10 years. The Smartphone has carried us from 2008 - 2023. The money that is being used today are already invested into the next 2 - 3 years of Semi Conductor manufacturing. That is 2nm or A20 this year and A18 / 14 in two years time. There is enough momentum towards A10 and A8 by 2030, 2032. Even if things slows down by then it is enough to run till 2035 unless something catastrophic like WW3 or Market collapse happening.

That said even if we somehow reach A5 in 2035, we are only at about 12x density increase. If we include system packaging, chiplet, interconnect advancement pushing this to 30 to 40x. This is still a far cry from the 1000 to 10000x compute demands from a lot of AI companies. And that is assuming memory bandwidth could scale with it.
