O’Neill cylinder is that big rotating cylinder space station format that uses the spin for artificial gravity.

At higher elevations the gravity will be lower. BMX bikes will be fun too. Make a big jump and you can go across the center and land on the other side, or go into a zero-gee part in the middle, which works out if you’re always inside a curve.

I’ve noticed ChatGPT gets less able to do precise reasoning or respond to instructions, the longer the conversation gets.

It felt exactly like working with a student who was getting tired and needed to rest.

Then I had above shower thought. Pretty cool right?

Every few months a new ChatGPT v4 is deployed. It’s got new training data, up through X date. They train up a new model on the new content in the world, including ChatGPT conversations from users who’ve opted into that (or didn’t opt out, can’t remember how it’s presented).

It’s like GPT is “sleeping”, to consolidate “the day’s” knowledge into long term memory. All the data in the current conversation is its short term memory. After handling a certain amount of complexity in one conversation, the coherence of responses breaks down, becomes more habitual and less responsive to nuance. It gets tired and can’t go much further.

I asked GPT-4 for a list of the most important threats to human civilization, their likelihood, and why they were considered threats.

GPT's output is also pasted into the comments.
