Can it be made reliable enough so it can provide exactness in the same way as classical computers ?
(Actually even for simplest of tasks they need heavy error correction.)
Can it work at normal temperature like todays computers ?
(Near absolute zero cooler at home would be very funny to have...)
Can it be adapted to any algorithm so it can
replace classical computers ?
(I think it can't, even on the most optimistic paper.)
If answer to any of the above is 'no' then for me it does not qualify as "anything good"...

And the statement is more or less already wrong. Encryption is ready to face quantum computing, or at least, it is preparing itself for it and is likely to be ready before.

In addition, the reason you mentioned for a plausible future does not look right to me because if they really reach the goal, they will lose their funding... so currently the best approach is lots and lots of claims and theoretical work, with some apparently successful experiment here and there, to make people believe in it - and this is exactly what we have today.
Anyway, if asked i wouldn't bet on quantum computer at all - actually i would bet against it.
I think one day they will find a limit, some basic law of nature they didn't know or anticipate, that they simply cannot bypass, and it will remain a lab's curiosity forever. This is just my view on it, it may be wrong of course. But remember nobody can claim to have fully understood quantum physics so who knows what is lurking...
