If Jeff Bezos could afford to spend $75 million on the Melania movie & $500 million for a yacht to sail off to his $55 million wedding to give his wife a $5 million ring, please don't tell me he needed to fire one-third of the Washington Post staff.

UX design so focused on optimizing for a given user task, while completely ignoring:
- goal achieved, i want to get back to where i was
- i want to immediately do goal again
- i want to switch to different goal
Way too many times is 3-4 clicks/touches just to... do more stuff with the same app.

Whenever I teach this, I like to remind my students that #rstats was informed by a lot of statisticians and NA means “I don’t know” so most logical tests and operators return “I don’t know”. x> 5? I don’t know. I have to know x first.

Still on Rstudio but I have it on machine. Does it simply go via the diff or does it read the whole repo? We’ve been discussing Claude and codex but they don’t seem to respect ignore directories (e.g. data)
