If you could instantly become an expert in any skill or field, no matter how random, what would you choose and why?

Self-motivation.

Surgery.

Why? Because I’m a surgeon.

Physics, all of it. It's such an interesting fields and I'd love to understand all the new discoveries without an article dumbing it down for me.

Public speaking. You could get a lot of stuff done and fixed if you can convince people to do it. Doesn't matter how good or smart you are if you can't convince other people.

Computer science/programming. So I could hack the planet.

Counting cards at a casino

Probably carpentry. It's highly relevant to what I do for a living. I have the tools and the physical abilities but there are big holes in my know-how

This question made me realize that I could become an expert in anything I wanted at any time; there is nothing stopping me. I guess I'm just not interested.

Survivalist knowledge would be practical in emergency situations. You'd get things like first aid, nutrition, self-defense... Seems pretty broadly applicable.

e: Thought of something. I want to be an expert assassin. Really top grade action movie shit so I can kill whoever I want while maintaining safety, secrecy, and connections.

If this implies success in that field, I would choose financial investing.

Using a bit of those funds, I could go learn and become an expert in many fields and enjoy each one. If your not learnin' you're dyin'

Music. Specifically woodwinds. Because I like them.

Japanese. It’s the one language that I need the most that I suck at learning. It just doesn’t make sense unlike Chinese. I have learned it for a while but it’s constantly flowing away from me.

Mechanical Engineering. Firstly because I am already studying it, but it’s also a super broad field, so if I’m an expert in all of it, I’ve just become an expert in like a dozen different fields.

Aerospace, biomedical, materials science, robotics, mechatronics, fluid dynamics, dynamic systems & controls, nuclear energy and all the other energy production types like fusion, even some branches in quantum computing and weird physics like Alcubierre drives.

Sure maybe it’s limited to the extent of where those fields are now, but I basically just became an expert in all of human technology.

Survivalist. Because, headlines.

Maybe competitive fighting video games for fun. My job doesn’t really let me focus on video games

Judo. bc it's freakin' cool, but I'm at an age where just doing the warm-up drills are too much for me.

Languages definitely. I want to be able to pick up new languages with ease

I want to be a renaissance painter

Don't monkey pawn me

An existing field?

I mean, if not, I think that it'd be a pretty easy call to be one that nobody is in, preferably one from the future -- now you have access to a bunch of unique and thus highly-valuable knowledge.

For me: Planetary science. We are making space discoveries every day. It'd be so cool to be in that room when that information comes across the computers and everyone discusses what the new discovery means.

I choose the skill of being able to open any food packaging (bacon, I'm specifically looking at you, here) quickly and easily without tools, weapons, or heavy machinery.
