I think most of people here in the forum are amazed with technology, and we have seen some technology gets obsolete, well, that could be one scenario for bitcoin. The quantum computes are on the way, and they will be really powerful. If the human create super computers that could be the end of bitcoin because with one simple command you can get all the private keys.

So, the new technology in some point will become a vulnerability for the old technology, and developers should be one step forward to avoid this happen.
Share your point of view guys.
I can't say that I'm very well familiar with quantum computing or the science behind it, but as far as I know, quantum computing is only applicable to a rather narrow spectrum of tasks. Well, it seems that breaking encrypting algos falls right into its scope of problem solving, but not all encrypting algorithms are created equal. So it looks more like an urban legend or myth that such computers once they come about will render the whole cryptography irrelevant. This is obviously not the case and in reality the devil is not as black as he is painted. This is what I think. If I'm missing something or just say something wrong, you are welcome to correct me on this matter!
I don't think it will take a lot of time to change an underlying algo once it becomes "endangered".
