I know this is a meme, but just in case someone doesn't actually know. CI saves literally thousands upon thousands of dev hours a year, even for small teams.
And a lot of users' frustration, especially on more niche platforms (Linux, ARM, etc.) - things look much better on release when the code have been regularly compiled and, hopefully tested, on all platforms, not just the one the lead developer uses.
As annoying as it is when someone else breaks the CI pipeline on me, it is utterly invaluable for keeping the vast majority of commits from being able to break other people (and from you breaking others). I can't imagine not having some form of CI to preventing merging bad code.
Hah, or my current one. Before we had CI you just directly committed to master (on SVN). It was incredible how unstable our build was. It broke basically everyday. Then one of the senior back end guys got promoted to architect and revamped the whole thing. Probably saved the company tens of millions dollars in man hours, at the very least.
Even better is when you restrict merges to trunk/main/master/develop (or whatever you call it) to only happen from the CI bot *after all tests (including builds for all supported platforms) pass. Nobody else breaks the CI pipiline, because breaking changes just don't merge. The CI pipeline can test itself!
I can't even imagine not having a ci pipeline anymore. Having more than a single production architecture target complete with test sets, Security audits, linters, multiple languages, multiple hour builds per platform... hundreds to thousands of developers... It's just not possible to even try to make software at scale without it.
If you fuck up the setup and deploy to multiple environments at once with each one set to rebuild an image/program things can get long. You really have to fuck it though.
