…he is still greedy (charging for his story) and oddly concerned with novelty clothing items (while he no longer knits Thneeds, his current outfit has a “secret strange hole in its gruvulous glove.”)

Incidentally “The Lorax” is really one of Seuss’s best. My favorite aspect of it is that the Once-ler’s characterization is very sharp: even though he regrets that his excess led to the destruction of the Truffula trees, …

me: *reading “The Lorax”* NOW…thanks to your hacking my trees to the ground, there's not enough Truffula Fruit to go 'round.
And my poor Bar-ba-loots are all getting the crummies because they have gas, and no food, in their tummies!
toddler: They should get sushi!

Toddler (sitting down in a restaurant she’s never been to): I’ve been here before! When I was little!
Me *dubious*: Really? When?
Toddler *thinks, nods*: When I was medium!

Toddler: I want two apricots, because I’m two-and-a-half. *Pause* When I turn three, I can have three apricots. *Pause, realization* When I turn four, I can have four apricots! When I turn five, I can have FIVE apricots!

How does math research change when the cost of trying your first dumb idea goes to zero?

University of Toronto mathematician Daniel Litt joins hosts Greg Burnham & Anson Ho to discuss what today’s models can and can’t do in math, and how far they are from doing high-quality research.

Uncle: I’m at work. What about you?

Continuation, on further discussion.
Me: do bees really make pizza?
Toddler: *long pause* they don’t have hands
Me: right, so how would they make pizza?
Toddler: Maybe stuffed toy bees?

Me: Did you know bees make honey?
Toddler: *nods* they make pizza too!

Her: “Daddy, only take ONE. Just ONE!”

Her: Just…one?

Toddler refused to eat her cheese after slightly tearing it, demanding I tape it back together. After some negotiation she was satisfied with me using “avocado tape,” i.e. laying thin slices of avocado over the tear.

Right, what I’m trying to argue here is that the likely reasons for this trend (AI tools) will probably contribute to atomization of the profession in general.

Not asking you to mourn it! But worth thinking about the implications the trend might have with respect to other things you might care about.

I think it's very reasonable to hope for better communities, but unfortunately I think we're just going to end up with fewer communities.

I don't think "strictly" is quite accurate--people might ask novel algorithmic questions for example--but yeah I think this is basically right, some Qs on MO are VERY hard.
