Back in college, I wanted this too. I triple majored in CS, biology, and chemistry. But when I looked at the impact I wanted to have and the resources I wanted at my disposal and compared them to an academic lifestyle, I saw a pretty glaring disparity.
The best way to actually command subjects is to work on them. Spend some time at companies doing the things you want - preferably in high paying jobs - and then start something on your own where you have to wear all the hats and submerge yourself in the technical details.
It's not as deep as academia, but it's certainly broad. This tactic might be what you're looking for.
And if you get exceedingly lucky, you might wind up with the capital and stumble upon the kind of unexplored areas ripe for growth that Elon Musk did. That's probably the ideal scenario - you get to work on incredibly interesting subject matters through hiring the best talent in the world. Use your team as a high level search and filter algorithm, and be present to learn and enjoy the process.
I'm nowhere near as successful but have employed people to do exactly that. It's not a bad alternative.
