My hope is that the death of x86 results in everyone flocking to RISC-V.
Reminds me when people wanted Intel to die and then they realized AMD started raising their prices with no competition and they tough that maybe AMD isn't their friend and is like any other for profit corporation.
So I have no idea why people want to see the most open PC ecosystem die. What kind of short sighted masochism is this?
Another part is the desire for a fresh start. x86 carries a lot of baggage. There's this idea that a new CPU architecture would somehow stop holding us back. Problem with that idea is that for the most part, x86 doesn't hold us back.
Then of course there's the remnants of the old RISC vs CISC debate that never quite died away.
People will always be fascinated by the what-ifs and if-onlys - "if only Sun had survived to the cloud era" is my personal favorite. It's harmless fun.
An open ecosystem in the way that historically emerged around the PC platform seems to be a completely orthogonal issue.
