Do any one of you guys think bitcoin should only be mined using cpu. I have been thinking about ethereum (Bitcoin's kid with good ux) merge.
ETH was also mined by ASICs alongside GPU, if not for the merge and if gear manufacturers were not under repeated threat of "we are going POS - your gears will be worthless" it would have been only a matter of time before ASICs dominate ETH.
Since BTC community had no intention or even real talks about going POS or switching to another algo, gear manufacturers invested billions of dollars in research in order to optimize ASIC miners for BTC.
Another important factor is the market size of each of these coins, BTC has always been a lot bigger than ETH, the huge potential profit that is ready to be milked out of BTC allowed said companies to invest and manufacture a huge number of ASICs that eventually killed GPU mining.
So really, unless you are talking about a small coin that isn't worth the efforts, or a centralized coin "at least at the development level" it will always end up being mined in the most efficient "way" whether that would be ASICs or hiring space aliens to mine it, you can't dictate what miners would use to mine it.
