This sums up how I feel about so many crypto related comments on HN. Just look at this thread. It's full of people confidently presenting 100% false statements as facts. Several of the comments contain something like "I looked into crypto years ago and then I saw problem X and discarded it." My guess is remorse because they could have been "early" compounded with confirmation bias.

To anyone who spent a few hours, days, weeks looking into crypto a few years ago and thinks you have any idea what's been going on in research in the field since then you're sorely mistaken.
