Academics Need to Wake Up on AI Ten theses for folks who haven't noticed the ground shifting under their feet

I'm not gonna touch most of this but two things:
1. The apprenticeship model of science was never supposed to be about the PI's workflow. The point isn't to have research assistants to help to publish stuff faster. Training the next generation researcher *is* the point. Because we care. Allegedly.

5/5 facct papers accepted, and also 2/2 chi posters (for some reason much more competitive than you might think). I'm pretty burnt out though, I haven't gotten a single phone call in two years of being on the job market, and the pressures to publish lots while also piecing together small grants 1/2

No walmart, vanilla flavored yogurt is not a viable substitute for plain yogurt! I don't want vanilla-flavored naan! This is my punishment for going full burrito-taxi on my weekly groceries...

Saw a random hyper-racist post, thought "Oh shit, did I accidentally open twitter again?" and yes, of course I did. I should install some filter to block me from clicking on twitter links.

I think that's my main issue with seeing AI mails, which are an instant ignore for me. I can't trust that you, the sender, care as much about this interaction as the words make it seem.

Please, please, please, don't send me AI e-mails! I will take typos and bad grammar instead.

The real teacher forcing was the saccharine "solarpunk" stories I made you rehearse.

Submit your RL papers to RLC!
This is now perhaps the best venue for RL researchers.

I still think the best alignment strategy is to write a lot of really hopeful and optimistic fiction about AI so that this saturates the pretraining datasets and future AI will be forced to roleplay the most benevolent versions of themselves we can think of.

Companies which make papers a hiring bonus should be told to p**s off. We are drowning in students who want to do "research" to get hired by Google... It's soul crushing

Every time I read too much about prompting, CLAUDE files, skills, etc, I feel the need to remind people that humans have an infinite capacity for magical thinking. The Romans were also REALLY convinced that there was a correct way to sacrifice a goat to ensure a good harvest...

Yes, I bow down to the infinite big brain that has to be behind that incomprehensible mess πŸ˜‚πŸ˜‚πŸ˜‚

Ok, but you haven’t even begun to properly make fun of the fact that in high school, we randomly switch to 5-15 (0-5 technically exist, but are all failing grades) and then high school final grades are translated back to 1.0-5.0!

What is the maximum time between submitting a slurm job and it actually starting that people would find ok for regular research progress?

Which proves that the issue is mostly off policy-bootstrapping, which is provably … difficult πŸ˜…

Claude jumps to conclusions faster than the most hyperactive undergrad I have ever worked with...

That's probably fair, I just thought to mention it cause Droid and OXE are also mostly just used for training (unless I'm wrong there)

My patience with graduates whose reaction to "AI will crash the economy" is not "oh, we should work hard on open source, policy, and figuring out how to help each other" but "f**k, you need to run through the doors so we can slam them close faster" has dropped to negative values. You have FAILED!

If you join an AI company because you need to be part of the few who will prosper as society collapses from economic turmoil, you have failed as a person and should be shunned. If your students express this attitude, you should sit them down and talk about responsibilities.
Build a better world!

Nice overview! I think the IsaacSim/Lab universe deserves a shoutout for locomotion training

Have you noticed how navigation apps include walking & waiting for public transit, but excludes parking & walking for driving? After being late a few times πŸ˜…, we finally did. We got curious: what if these apps account for parking?

That would be my question: how often are candidates with three papers even invited? Random sampling at both UofT and IT Austin suggests… never

this is my reaction as well: we just need to hire more faculty to advise them

Ah I understand your point! In many such cases you can still probably point to the 5 most pivotal work that intergrate the smaller steps?

Even then, a student from a rarely publishing lab will often barely generate attention on 5 papers if that is all they got. Since universities run on citations, you are screwed, even if the work is good.

Impact is not independent from the attention paper mills produce. A good paper does not create impact on its own.

I had one call per interested lab (I believe it was 4 or 5) and then I got an offer that was in the 2019/20 season

We're thrilled to share that the Call for Workshops for this year's @rl-conference.bsky.social is now live!

As Workshop co-chair (alongside the wonderful Raksha Kumaraswamy and @claireve.bsky.social) we are looking forward to seeing the proposals for workshops that we receive.
