>In light of the recent hilarious paper around the current state of quantum cryptography
I assumed that paper was intended as a joke. If it's supposed to be serious criticism of the concept of quantum computing then it's pretty off-base, akin to complaining that transistors couldn't calculate Pi in 1951.
> how big is the need for the current pace of post quantum crypto adoption?
It comes down to:
1) do you believe that no cryptographically-relevant quantum computer will be realised within your lifespan
2) how much you value the data that are trusting to conventional cryptography
If you believe that no QC will arrive in a timeframe you care about or you don't care about currently-private data then you'd be justified in thinking PQC is a waste of time.
OTOH if you're a maintainer of a cryptographic application, then IMO you don't have the luxury of ignoring (2) on behalf of your users, irrespective of (1).
