Having strong competition between the CPU vendors is always a good thing. AMD has made mistakes, but it's hard to argue they don't deserve to outsell Intel for a change.
I hope they use much of this windfall to invest in improved products in the future. It's unlikely to impossible that Radeon or Instinct will ever be more popular or faster than its competition, but it shouldn't languish, and the Zen series should keep running circles around Intel.
There is arguably no particularly strong competition. There would be strong competition if Intel and AMD had to compete with x86 CPUs from Apple and Qualcomm.
Or if Intel and AMD GPUs had to compete with Nvidia GPUs ... wait, they do, and they are absolutely losing.
Hopefully they don't completely swap roles completely, with Intel being incapable of competing and AMD stagnating without competition. I'd rather they both be competitive.
