Although I do think between Python and Java, just pick your poison, they're not night and day. Unless you're writing 1990s Java consisting of factories of factories which is more to do with library style and over-conventionalism (back then when people were writing APIs after reading GOF). Even in 2004 I don't think there's much credibility in knowing both languages although I wasn't around.
What I find stupid that a lot of recruiters and jobs look for certain languages/technologies and require X years of experience in them. Sometimes requirements predating the existence of certain frameworks. Makes sense if you for some reason need a Kubenetes guy but mostly not.
But I still see this happen more than 20 years later when brilliant ex-Java folks are doing Python.
Java has this weird cultural inertia which reminds me of "Five Monkey Experiment".
I wish more of those weren't flagged to death when people post them here.
Here's a deeper explanation from a random Google search result.: https://www.businesswritingblog.com/business_writing/2022/05...
I am a programmer and a published book author (8 books so far and over 35000 sold copies). I wrote a pile of shit, too, but it helped me become a better coder and a better author.
Then again, maybe he's asking for it, given that he calls his blog posts "essays". Lol.
