Well, in my experience this is equally (or even more) dangerous. I've seen when the engineers take over and it turns out that they are not necessarily better (at least not 100% good) at "simple" things such as estimating within a 10-20% bounds and similar things - even in organizations that are supposed to have some of the best of them. Rather, in organizations that believe in this kind of thinking (if we could just get rid of management and do it ourselves we'd be so much better off - kind of reminds me of NIH-syndrome) are typically worse off. It's like people who don't believe they are susceptible to ads - they are generally the ones most susceptible....
Yes but .. huh? How many developers claim to be good at estimation if not for their managers?
My experience has been that devs would much rather not make estimates because they know they can't do it, and when their management is itself made of engineers, they aren't asked to. Engineering-led businesses find other ways to avoid the need for estimates.
