How future proof is Crypto? Do we think about where technology will be on 50-100 years?

I’m not exactly a nay sayer. I’m an investor but, these are things I wonder if anyone else thinks about.

Considering we’ve gone from the first cars to basically carrying a tricorder in a little over 100 years, what are we gonna do in the next 50? I’ve seen stats saying that the fastest computers on the planet would take years to crack a passphrase even knowing the words.

Technology moves so fast and most tech becomes obsolete. Calculators used to have vacuum tubes. Can crypto really be the way or will it be useless technology in 50 years?

I know it’s super hypothetical but I would imagine and alien would look at bitcoin like a 2nd grade math quiz and could hack it in about 2 seconds? If we don’t kill ourselves first it’s a matter of time before we see it as the same.

Or so we eventually do away with money because it’s only a matter of time before we can create gold in a lab too.

Maybe I watch too much sci-fi but I ponder these thoughts because a lot of investments (bets) are made thinking 20, 30, 50 and more years ahead.
