I have 10 years of experience. I am a reasonable engineer. I can tell you that about half of the hype on twitter is real. It is a real blessing for small teams.
We have 100k DAU for a consumer crud app. We built and maintain everything in-house with 3 engineers. This would have taken atleast 10 engineers 3-4 years back.
We don't have a bug list. We are not "vibe coding" , 2 of us understand almost all of the codebase. We have processes to make sure the core integrity of codebase doesn't go for a toss.
None has touched the editor in months.
Even the product folks can raise a PR for small config changes from slack.
Velocity is through the roof and code quality is as good if not better than when we write by hand.
We refactor almost A LOT more than before because we can afford to.
I love it.
