> I can

You can because, I guess, your project may have a small scope, few people working on it, no dependencies etc.

I cannot, because each line that I change has an effect in millions of other lines and hundreds of other people, and millions of users.

Different situation, different needs.

Shipping the happy path faster is easy. The part codegen hides is the month after, when teh weird edge cases start colliding and you're stuck reading a pile of code no one would have written on purpose.

That trade can still make sense for a throwaway MVP. Most people underestimate how fast the maintenance bill add up once the first non-obvious bug report lands.

I read that as you have never been debugging a production issue at 3am while losing data and/or revenue.

Can you provide some examples?
