They indeed are quite spoiled - and that's not necessarily a good thing. Part of the issue is that our CI was good and fast enough that at some point a lot of the new hires never bothered to figure out how to build the code - so for quite a few the workflow is "commit to a branch, push it, wait for CI, repeat". And as they often just work on a single problem the "wait" is time lost for them, which leads to the unhappiness if we are too slow.
