That is neat, I did not know this method of constructing a gold ratio. Once you have a golden ration it's easy to construct a pentagon (with straight-edge and compass).

I'm not from the US, but here in Australia, the 2026 BYD atto EV is priced at 24k AUD. That's 16k USD. Also the infrastructure is there as most homes are connected to the electricity grid

Add to that that the demand for imaging is not fixed. Even if somehow imaging became a lot cheaper to do with AI, then likely we would just get more imaging done instead of having fewer radiologists.

This seems like an odd error for the article to make. The great pyramid in Giza is nearly 50% taller, was built nearly 2500 years earlier, and still stands today.

Not sure why this comment is getting downvoted. The article itself states that:

> "This is an observational study, and as such, no firm conclusions can be drawn about cause and effect. The researchers also acknowledge that their study was retrospective, and they weren't able to account for dose or length of gabapentin use."
