That moment when you enter a university campus and all bets about the path-connectedness of two places you can see are off

@christianp One of the many idle ideas I've had for video games that I will never, ever, ever, ever do a thing about is creating a Campus Map Tycoon game, putting in buildings and walkways and roads and bike lanes and parking garages to make sure that technically all possible traffic by any mode is provided for, and yet it can't happen.

I asked ChatGPT about primes ending in 2 to make it prove a point and it proved the point far better than I could have hoped for.

Please do not be a fool who trusts ChatGPT with anything outside your field of expertise, and even then double or triple check what it tells you if you must use it.

I asked ChatGPT about the percentage of numbers in the last sequence that are odd. It answered with a list of "the first 100 primes ending in 2" which started 2, 3, 5, 11, 31, 41 … and it then claimed that out of those 50 are odd while the others are even, and that therefore 50% would be odd.
I asked ChatGPT if there are only four prime numbers that end in 2. It confirmed this saying the four prime numbers ending in 2 were 2, 3, 5, 7 and that no prime number greater than 7 could have 2 as the rightmost digit because they would be divisible by 2. I then asked ChatGPT if there are five prime numbers that end in 2. It apologized for its oversight and confirmed this saying the five prime numbers ending in 2 were 2, 3, 5, 7, 11 and that no prime number greater than 11 could have 2 as the rightmost digit because they would be divisible by 2.

@bhawthorne @abananabag @alinanorakari Still, it's so very thrilling to see someone finally shaking up the epistemology industry.
