This thread is HN jumping the shark for me. The merge is freaking incredible. Switching the engine of a $60 billion financial network in-flight. Permanent power savings the scale of a country. An incredible coordination between a huge number of diverse parties all over the world. Everything open source. And all we get is a rehash of tired old arguments against cryptocurrencies. This was originally a forum for hackers…
I don't know if you ever argued against that massive energy footprint as "FUD". But I do find it pretty hilarious to see a crypto proponent now use that as a positive. "We're not wasting country-sized amounts of electricity anymore!"
FWIW, I don't think most crypto-critics (yours truly included) argue that it's not technically interesting. We argue that it's tech in search of a (mostly) non-existent problem, that has a whole host of very negative externalities.
