Why a Twitter post and not the official Google blog post… https://blog.google/innovation-and-ai/models-and-research/ge...
The official blog post was submitted earlier (https://news.ycombinator.com/item?id=46990637), but somehow this story ranked up quickly on the homepage.
Agreed - blog post is more appropriate than a twitter post
Just normal randomness I suppose. I've put that URL at the top now, and included the submitted URL in the top text.
