As long as there are consumers paying for hardware ownership there will be businesses willing to sell it to them. The worst scenario I could imagine is that one has to pay a premium for fully-owned hardware simply because consumer's desire for it becomes an oddity and it is thus sold in low quantities.
The current AI-induced shortages aside, the times have never been better in my opinion. There is overwhelming choice; ordinary consumers can access anything from Raspberry PIs all the way up to enterprise servers and AI accelerators. The situation was very different in the 1990s when I built my first PC.

That's not true at all.
There are a lot of people willing to buy smartphones with small screen or smartphones with Linux or any other OS than iOS or Android.
But those people are not enough to justify the gigantic initial investment that is necessary to provide viable products in this market. And the existing actors aren't interested in those niche.
