Today, 3 had a massive tantrum because her leggings don’t have pockets and then she realized that none of her pants have pockets except the jeans she doesn’t like. And - yeah. A toddler can grasp what the entire fashion industry seems to miss about women’s and girls’ fashion.

Every conversation about bike lanes is like: "Car crashes kill a huge number of people every day, including pedestrians, cyclists, & car occupants. Good bike infrastructure has been shown to make everyone safer (& doesn't increase congestion)." "But sometimes cyclists break rules & hit people!"

I understand that funding bodies want to go all in on AI as the shiny new innovation thing. But if all the grants start going to AI at the expense of everything else then the research sector is going to end up looking like a farm with dozens of threshers hacking away in a field with no wheat.
