I don’t spend much time on @bsky.app & mainly cross-post from Mastodon 🐘. But, if you follow @ap.brid.gy, you can bridge your account & let people (like me) follow you from the fediverse, which is very cool.

With the number of applications to most schemes measured in the tens of thousands and success rates in the 5%-10% range, the system is saturated. Science funding, and hence science careers, is no longer a meritocracy — it’s luck of the draw.
