r/TeslaInvestors and r/AMD_Stock are some of the worst. I can easily imagine some in the latter organizing to get RISC-V banned in the US.
The loser from RISC-V is clearly ARM because it's not nearly as hard to produce a low-power processor with mid-level performance, which is the core of ARM's market but RISC-V allows the vendors to avoid paying for the ARM license. And unlike x86, most existing ARM software isn't distributed as third party binaries tied to a particular architecture and could easily be recompiled for something else.
>neither of which RISC-V would do any time soon.
The latter, maybe.
The former, as soon as 2024 (e.g. Tenstorrent Ascalon)
But it would matter to ARM.
That makes the company's supporters intolerant of criticism because they've been conditioned to expect criticism to be in bad faith. Which continues even after the short sellers have given up or been eviscerated by margin calls.
