We can look in the past to see what hasn't changed. Given the rate of innovation in the field, it's fascinating to see that some widely used tools have been here for 30-40 years or more. Unix, bash, vim, C, C++. It still worth investing in these seemingly archaic stuff. Notably C++: the cool kids want to learn Rust, but C++ is hard and we'll need to maintain all the existing code forever!

And of course, maths. I graduated in maths decades ago, and I always find it amusing when I see some tutorials on linear algebras making it to the top of HN, like if it was some fashionable new cool technologies. That being said, my math knowledge hasn't transferred in software engineering skills.
