No thats a sham, it was already debunked:

But I mean is if physically possible to combine many qbits together to break all encryptions and create a totally 0 privacy society where the quantum computer can even calculate and predict your behaviour from your genes. That would be horrifying.
Yes an AI replication system is also worrysome, it would create a virus that would start growing and destroying and assimilating everything in it's path, like a Borg cubes from Startrek.

Its very horrible where the technology is headed.
