I used to think this 20 years go. I was also wrong. The state of the art of software development does NOT move fast, it moves glacially slowly. The fundamental technologies of 20 years ago are very similar to what is in use today. The tools are similar, the languages are similar, the frameworks and libraries are similar. Mostly, they have simply now more polished and have a few more features. A handful of things that were leading edge 20 years ago have gained popularity. These include things like object frameworks, event-oriented programming and the like. Some things that some call new are actually things that existed in the 80's that have just come back into fashion. Take asynchronous programming using callbacks (popular with javascript/node). We used these techniques in the late 80's quite extensively. There are a few things on the leading edge today that did not exist decades ago (or at least I wasn't aware of them). But these are far and few between. The basics though, those have not changed. What changes rapidly is tech fashion (for want of a better phrase). When I hire, I simply do not care if you know framework X or Y. Or even if you know language P, Q or R. What I care about is if you 1) truly understand the fundamentals and if you can 2) apply that knowledge to create high quality software.
