Vacuum tubes are too complicated, let's use solenoids and other electromechanical-stuff-that-i-dont-know-the-name, with 120V it's safe enough for children ?
I'll see your bet and raise it! My new computer:

This is why I want to create a dream computer made with vacuum tubes. Transistors are just too dang magical. ?

The funny thing is I understand transistors at a physical level better than I understand vacuum tubes. In the 70s, there were not various vacuum tube electronics magazines explaining them to me ... it was assumed anyone who cared already knew.

In reality, my understanding of either is pretty superficial. I just figure there's always a more primitive technology that someone can pull out of their posterior because technology X is just too modern and difficult to understand.

I don't mind the use of FPGA's and CPLD's. I see them as ASIC's.

Because they are ... little ASICs with an eraser so that their fabric can be repaired as needed (from one perspective, anyway).
I realize that not all FPGA are "reprogrammable" ... some are like a PROM, write it once and throw it away if it doesn't work. But reprogrammable ones are more and more common.

Many (possibly most?) FPGAs have one-time programmable fuses in addition to SPI bootstrapping. That way a bad actor doesn't flash a new design onto your stove and have it think that it needs to run the gas for 300 seconds instead of milliseconds before igniting it. And your company doesn't have to pay to have the design fabricated into an ASIC.
