You know what's funny. I would not call the environment you're describing as a tech company. I would call what you're talking about a tech-enabled company. If you are working at a tech-enabled company, then I 100% agree with you about moving to management becoming inevitable. Tech-enabled IC's are basically rendering JSON/SQL/NoSQL in on Desktop/Web/Mobile. If you're company is just spinning up .Net Core/Node/Django/fill-in-framework-here to build a website to show some data, that's not a tech company to me.
When I say tech company, I'm talking about companies where software engineering skills actually matter. where a O(n²) algorithm also will cost your business. In my definition of a tech company there are tons of new things happening. Look at the spaces like AR, self-driving, rocketry, and machine-learning, and computational photography — no one in any of those fields is doing the same thing they were doing even 2 years ago.
