This. Plus if you get to be really good at something and extremely knowledgeable on a topic you can get to be able to claim nothing about your expertise level. (Dunning–Kruger effect, gone right).
The only downside is that people will pigeon hole you, so if you become expert at something people will keep you doing it rather than promote you to something you cannot do (according to them). This can be bad if you are a creative at heart and get pigeon holed as a techie.
So maybe master two things in unrelated areas. Get the tech string to your bow but add on another, e.g. knowledge of a period of history or a craft.
