I believe alt-coins will be the gateway drug to Bitcoins. Although, I can't really say that any of the coins I've seen so far are terribly innovative beyond BTC, which is really surprising. Exceptions would be NMC (domain name system), XPM (prime number discovery), DVC (contributing to open source development), MSC (distributed exchanges and betting built on top of BTC). XBT looks extremely promising as well. I think any coin which has ties to something outside of itself will become highly coveted. In that respect, Bitcoin is quite lousy. Then again, so are fiat currencies in general. It is unfortunate that we have to replace one faith based system with another. However at least this is an improvement. Once inexpensive, room temperature superconductivity is cracked, as well as high density power generation and storage, I believe energy will be the next currency. That's something you can actually put to use.
Good luck with your dreams. If you want to have any chance of seeing them, first something has to be done about the fact that GE and other major corporations are sitting on all the patents for any form of energy production that can't earn them revenue streams. There are several technologies that were first demonstrated in the 60s that could generate more power than a home could use for decades with no maintenance or fuel. Each of the inventors of these technologies met with an offer they couldn't refuse. As long as the patent system allows this (and they will because the companies will spew B.S. about it not being economically feasible for them to fully develop it yet), we won't see anything that could hurt their bottom line in the light of day.
That said, there are still places on this Earth that believe that you shouldn't be able to own ideas. Likely, those areas will become advanced enough to reinvent some of these things long before we see patent reform or a company make a move against their bottom line.
Can you show me those patents? Also, once they expire, anyone can manufacture based on them. If there is any tech suppression happening, it is well before the provisional patent filing stage.
Also, I do agree that our patent system is incredibly broken (like damn near all laws, bought and paid for by
).
