I don’t disagree that 3 seems valuable, but at the end of the day scientists are just people and should not shield themselves from having to validate and communicate their work given it’s impact on normies.
Consider there is still plenty of ways for scientists to communicate undistracted; a site such as this does not mean other forums are obsoleted. Private channels will still exist.
Email allows inline git reviews and comments, without HTML, CSS, JS, and the microservice jungle needed to host a web app these days.
I follow a few of the Linux kernel mailing lists and frankly I am jealous af; no Slack, no Jira, no web UI I can accidentally refresh which flushes state and deletes the comment I was writing. Was less bandwidth hungry.
Hosted UI just seem like a huge waste and a whole lot of agency capture by VCs. Just release a Docker image, give me an API key.
Manual labor used to be applied to these things. One could argue the fossil fuel industry got us hooked to petrol solutions in search of a problem.
Look at us too addicted to our inventiveness to get our hands dirty, a little sweaty outside the air conditioned gym, or give up a grass lawn.
