I personally feel that this is being brought up more and more to create FUD and panic. It may be true that quantum computers are indeed that sophisticated but until there is evidence that can actually be concrete why believe in something that is not even certain.
Breaking the bitcoin key is not as easy as imagined and they try to claim that it is very easy to do without providing real evidence and exaggerating it from now on is it not a ridiculous thing.
That's what I mean, there is no evidence or real threat from QC to bitcoin, so far. It's all speculation, theory and as we all know, reality and theory have a huge difference and gap. So, as long as there is no real concrete evidence, we need not worry about the threats that come from such empty theories.
We all know that bitcoin was once hated by the whole world like government, banks, traditional investors...they all don't want bitcoin to exist and want it to die. If QC can threaten bitcoin, why don't they pour money into developing it and use it to destroy bitcoin? Obviously, they are not sure about that either, it is just a theory, nothing more. So we don't need to worry about unreal and exaggerated things.
By the time we reach something concrete, there will be ways to avoid it entirely, so, yeah - we don't need to be scared before QC becomes more attainable by everybody and working at all.
