That only natural for people that are not interested in technology or programming itself. People that are interested in new technology and keep learning new things will become more successful as IC and have more opportunities. If you are lucky, and you start with something that is popular long term like Java, you can find decades of stable employment in big corporations. If you are unlucky and start with PHP/Perl you either switch stack or you will stuck in low paying jobs maintaining legacy apps. Programming is less forgiving than other industries, as there are more fundamental changes over years. On the other side, huge demand make it easy to find and change job. You could make AWS certificate and some JS/Python/go training, update LinkedIn profile and wait for offers to flood in. In less than 1 month effort you could rebrand yourself and find jobs in new stack.

There is good satire of the stone to Bronze Age transition. https://www.youtube.com/watch?v=ZHGafC7zOUE
