That's what the mathematicians seem to be thinking, I'm still waiting for them to fix math!
Seriously though, I guess you're right. The biggest struggle is with myself, not with math. I could do it if I put some effort into it, but somehow whenever I start, even with the best intentions, math always seems to make me angry and desperate. I'm not sure where it comes from...
I'm about to predict the future of IT, and we all know how well that works.
But anyway, quantum computers will probably for a long time be large expensive things mostly used to simulate quantum systems. A couple of integers will be factored (but mostly as benchmarks), some simulated annealing will be done (because it tackles such a wide range of problems), and a couple of other things, but the killer app would be quantum systems, for physics and chemistry. Later, when they finally manage to make them small/cheap enough for more casual use, you're probably just going to use some library that you can hand your data and magic happens. Probably in the quantum cloud. The quantum desktop .. maybe. I'm not convinced the average user needs that kind of power for anything ever, but that kind of prediction is usually wrong. Maybe we'll simulate physically-accurate photons just to render our games or something. And there won't be a switch to quantum computing, it'll be extra. Conventional computing will remain relevant.
As the number of problems to solve with current technology is almost limitless, I don't think you'll have a problem. Understanding quantum algorithms will only be important for problems that dwarf the current regime in complexity. Even if quantum computers become commonplace, you can still get the current level or better of performance out of them with the current idioms. Classical Mechanics is still an excellent approximation for most cases.
A few years back I had a mole cut off in my armpit to be sent away for testing (no cancer... yay). They cauterised it with a hot poker, and blow me down if we don't smell like pork crackling when singed!! Put me off pork for a good few minutes!!
