No, you are dismissive because you don't care about the use-cases.

The R.Pi 4 , 400, and the 500 are great models. Consider all the advantages together:

i= support for current Debian

ii= stellar community

iii= ease of use (UX), especially for people new to Debian and/or coding and/or Linux

iv= quiet, efficient, low power and passively cooled

v= robust enough to be left running for a long time

There are cheaper, more performant x86 and ARM dev boards and SOCs. But nothing compares to the full set of advantages.

That said, building a $3K A.I. cluster is just a senseless, expensive lark. (^;
