The thing generative text-bots have mostly taught me is that there’s a sizable number of my fellow academics who hate to do the things that are most central to our job

I'm never going to be okay with the idea that I'm supposed to sit politely while people talk about using ChatGPT to do their research! I actually do this science stuff because I enjoy it, and I think if you hate writing your own papers or parsing your own data THAT much you should do something else!

A lot has already been said about AI and citations but there is a central point I feel we're missing: as academics, we work hard for far less than our time is worth to write papers that will be read by maybe a few dozen specialists if we're lucky.
If you don't love doing it, what's the damn point

Yay, right?
The *entire annual budget* of NSERC is $1.3 billion. And he's cutting that.

Looking more and more like the distinction between the South China Block fauna and western North America is a lack of insufficient sampling. Expect more here.
In the early Devonian #lungfishes — now considered "living fossils" — were all the rage!

I am seriously considering setting aside a large percentage of lab class time for report writing, because the choices are making data analysis and writing an in-class activity or just cutting them because they're meaningless assignments.
this is hilarious and miserable. just so tech bros can have their dystopia moment, students have to lose all accessibility provided by remote technology and we the professors lose the flexibility and convenience. but progress, amirite?!
For the moment, there is no alternative.
