Your contention was that the extra performance provided by AMD was not usable, not that it wouldn't win in the market. So we were indeed discussing who had the best tech, even if that's not all that matters for commercial success.
Because those things go hand in hand, the large majority of developers aren't doing HPC, Fintech or work at FAANG, or even posting on HN and Reddit, rather they are the so called "dark matter developers" whose applications must run on those Core i3 and i5 used by the consumers at large.
As such most developers only bother to use what they already know and take very little effort for adding any form of parallelism or concurrency to their applications.
Android and UWP since the start have taken architecture decisions that forbid synchronous code, because both companies came to the conclusion that if that would be available, the developers would write single threaded code as they have been doing for years, so they took that option out of the platform.
You've just switched to a totally different discussion. I don't agree with it either, because I see everyone around me in home-office, not even developers just workers in a normal corporate environment, that can definitely use that extra performance. But that wasn't the point being discussed.
