if it showed signs of going that high tech companies would likely switch to cheaper metals as alternatives and phasing silver out. it probably would not sky rocket for that reason alone.
have you heard of graphene? it will most likely replace silver in terms of its use in electronics/technology because it's way cheaper and just as effective.
If silver will go up, it would have done so since time past...
why would it have gone up? PM's typically have an inverse relationship to fiat - when an economy is strong, PM's typically don't perform well as the perception is that they're safe haven assets. the gold:silver ratio is way off and every expert will tell you it's because silver prices are suppressed
on purpose.
