All it would take is for lithography equipment/chmicals/etc to start being sold to anyone at an affordable price... so, maybe in 50 years.

On that note, you could technically just buy the chips and spend an inordinate amount of time and money building the PCB and firmware.

50 years is optimistic. The equipment needed for vacuum, plasma sputtering, and masking hasn't changed much in the past 50 years.

Sure, if you want to make a 1 um process you can do that with a purchased wafer, some chemicals, and a spin plate. If you want to make a nm-scale process you'll need to have a serious budget.

chips, pcb and mask (for the soldering pasta) are not so expensive. Soldering remains difficult and time consuming
