Respectfully,you know nothing about what you're talking about.
Async work is already the norm for some companies, even prior to moves to full remote work. I personally know teams in renowned companies which before COVID already split teams working on products between the US, Europe, and India. They stuck with full async because it worked, and worked better than alternatives.
With COVID, the whole world went full remote due to necessity, and I personally know teams whose output improved significantly with the move to full remote to the point where they stuck in remote by default.
> Personally, I think it should be coupled with an investment in HR to get more qualified and motivated people working on the problem.
I disagree. What I'm seeing is a lazy, conservative mindset of people who feel scared and threatened by a reform shaking up the very core of a system they feel benefits them personally.
