>>>> In a functioning org, there are lot of professionals depending on correct estimation to do their job.

A side effect is, no there aren't. Allow me to explain that catty remark.

The experienced pro's have figured out how to arrange their affairs so that delivery of software doesn't matter, i.e., is someone else's problem. The software either arrives or it doesn't.

For instance, my job is in technology development for "hardware" that depends on elaborate support software. I make sure that the hardware I'm working on has an API that I can code against to run the tests that I need. My department has gone all-in on vibe coding.

Customers aren't waiting because the mantra of all users is: "Never change anything," and they can demand continued support of the old software. New hardware with old software counts as "revenue" so the managers are happy.
