Scientists are not fast at abandoning established ways of communication. I mean they still publish the same way as a century ago, its just now digital too. It took a whole friggin' pandemic for life science researchers to embrace the concept of pre-prints. 8 months to move from twitter sounds almost fast.

Thanks, Elon. This is why we can't have good science.

In STEM fields communication with others is key in improving your research. It is not easily to rebuild these “links”. Since Twitter was the biggest hen in the henhouse, it was a forgone conclusion.
