Great article https://blog.bradfieldcs.com/in-2017-learn-every-language-59b11f68eee on why to learn more programming languages.
Did you know about the existence of brainfuck programming language?
Hello World in brainfuck 😀
The article mentions http://hyperpolyglot.org/ which has a great side-by-side feature comparison of some programming languages.
… that’s just the first ten years. After that, nobody can think of a single feature that they really need. Is there anything you need that Excel 2000 or Windows 2000 doesn’t already do? With all due respect to my friends on the Office team, I can’t help but feel that there hasn’t been a useful new feature in Office since about 1995.
So, it takes a long time to write a good program, but when it’s done, it’s done. Oh sure, you can crank out a new version every year or two, trying to get the upgrade revenues, but eventually people will ask: “why fix what ain’t broken?”
slow down, or your existing customers will stop upgrading. They’ll skip releases because they don’t want the pain or expense of upgrading.
