“I found the black and white color palette simplistic and, frankly, condescending.”
There should be book clubs for babies. "I enjoyed the crinkliness of this one but I have to say the little mirror at the end was a bit predictable."

Twitter accounts are based in Russia. BlueSky accounts are based in homes with, frankly, too many books, plants, obsolete cables, and pieces of rustic pottery, that could do with a bit of a tidying up, to be honest.

Adventures in non commutative arithmetic
Trying so hard not to pass my disdain of legacy curriculum publishers onto my kid, but y'all make it so hard when your little online program marks a PARTIAL PRODUCTS problem wrong because he didn't list them in the order you wanted him to. 😒

A SQUARE IS A SHAPE, YET ONLY HALF OF SHAPES ARE SQUARES
Are all squares one square or many squares because i think we're dealing with the same infinities then and there actually is a 1-1 count of squares and shapes. [I will see myself out]

I would also like to propose a ban on anyone who thought an internet-connected teddy bear would be a good idea. And on anyone who facilitated their manufacture or distribution. Y’all can no longer work in tech or toys.
I feel like a ban on internet-connected teddy bears should be a pretty easy legislative move. No need to define AI or anything. Just no teddy bears that connect to the internet in any way.
