Async Collaboration - why is it needed?

I have been fascinated by power of async collaboration.

A bit of a background - I used to manage a team of > 150 people, (30+ developers, 10+ product and design, 100+ content creation). What I realized was productivity takes a huge hit as people in your team increases

1+1 = 1.5

Countless meetings (which could have been resolved via a slack message), bottlenecks not getting revealed on time leading to further delays etc. I started focusing a lot on async collaboration using mix of slack, loom & notion.

I believe async collboration tools built for developers on top of existing platforms like VS Code, slack can lead to massive productivity gains ( esp in remote / hybrid workspaces) through solving problems like

Resolving errors faster through tribal knowledge of the team
Streamlining the deployment process - knowing which code to take, what has been tested etc
Onboarding to a new repo

What are the other problems do you feel which are crucial, unsolved and potential opportunities for async collaboration?

P.S - I created a small plugin for VS Code for developers to share their errors with fellow developers easily, would love to hear feedback -
