here's what I'll grant the OP... the people who are specifically in the market for a 3090 calibre graphics solution (and they know who they are) almost certainly won't be satisfied with apple silicon for their needs right now. apple invited this criticism by bringing 3090s into the conversation. sure there are technical metrics where it can be somewhat comparable - but at the end of the day M1 is not a gaming platform at this point, nor is it a path-tracing beast, and those are likely the overwhelming use cases for people who'd be in the market for a 3080 or 3090 system right now.
that said, I'm pretty sure nothing about apple's chips are slow. they are balancing performance (which is legitimately great in some areas, and more middle of the road in others) with considerations like heat, energy consumption, battery life, fan noise, etc.
for a lot of people's needs, that balance is likely an appealing one. I'd still love RT cores to speed up my 3d work, but this machine gives me more than adequate performance in a package that is generally more pleasant to use when I think about it overall. we'll see where they go in the future, but I think their general strategy for right now is plenty good.
