Immediately throwing generic into the ring feels wrong to me. So I want to ask you first: What is the motivation or personal need behind your idea that you want to specialize?
- Becoming famous/known in a tech niche like Uncle Bob oder Martin Fowler? - Founding a tech-driven unicorn? - The feeling of admiration of your colleagues and potential employers? - A high salary and high paying job over the next 10 to 20 years? - The intelectual stimulation most of us tech people feel when we play with new shiny things?
I feel like all of these reasons are valid, respectable and OK. Different answers/picks/strategies might apply though.
Seeing forward for you reply. I'm happy to help!
