Computers clearly existed before the 1970’s even though nobody was buying personal computers back then. We are at the earliest version of self driving where it’s not affordable for individuals and the use cases are very limited, but that’s not nothing.

The self driving car you want to buy doesn’t exist, but they are already providing a valuable service. Saying well VC’s want to replace all Taxi drivers and all Long haul truckers and all … just means that development will continue but that’s true of most products. We hardly say the CPU doesn’t exist because Intel and AMD are still spending billions on R&D. All existing self driving car investments are really just peanuts compared to what companies will spend as the market matures and profits roll in.
