Yeah, one of those technologies is fiat money... We have a solution now, that could solve that problem, but despite owning what I currently consider a moderate but decent amount of said solution since around the first halving (more back then, of course, I was mining and buying stuff with it), and having listened to probably 100-200 hours of podcasts, read one-and-a-half of Saif's books, etc. etc., I'm still not anywhere near convinced that hyperbitcoinization will inevitably come, or that the value won't go to near 0. (Don't worry, I'm hodling an amount I've determined, just in case.) I guess I'm a pessimist - I'll attribute that to, particularly me being very privacy focused, learning in fiat world that change generally is in the negative direction...
