I understand the hopium, but the article offers some convincing facts. I wouldn't just blindly throw this emerging technology off the table – Bitcoiners are, after all, in a similar boat as part of a revolutionary, disruptive tech that many still just wave off. Billions of dollars by powerful entities are being poured into this, and given the grey area the Bitcoin blockchain is legally, there is hardly any reason to believe Google (or the Chinese government) wouldn't try to crack it given the potential gains. Quantum may well be another paradigm shift and Bitcoin would be still part of the old world of binary computing in such scenario.
