Astronomy usually has that kind of "Lovecraftian" sense of cosmic insignificance when you put things to sacale. Also, being alone at 3am in the middle of nowhere, cold and kind of sleepy, looking at a gas cloud lightyears away, adds to it. But it is also fascinating.
honestly the times I was on a proper telescope, I was shitting myself making sure I made the most of the time going down my list of targets and not getting something wrong and pointing at the wrong star or getting the wrong setting. that and the daemon that had to be restarted every half an hour or so because it crashed. I did not have the energy or time for philosophy. I guess that's the difference between the phd student and the professor haha!
Type hints and/or stronger typing in other languages are not good substitutes for testing. I sometimes worry that teams with strong preferences for strong typing have a false sense of security.
Writing and maintaining tests that just do type checking is madness.
Dynamic typing also gives tooling such as LSPs and linters a hard time figuring out completions/references lookup etc. Can't imagine how people work on moderate to big projects without type hints.
Because, as a senior, you usually already know intuitively what a good solution looks like, and you can quickly discard model responses or suggestions that do not align with it.
