ChatGPT was publicly released on November 30, 2022

Thanks for pointing this out. As the plot doesn’t display the correct date for the release of ChatGPT, it’s either based on incorrect data or mislabelled (it might intend to mean some release of GPT). In any case deleting this HN post as the referred to source is dubious. EDIT: I don’t think there’s a way for a non-mod to delete it once commented on.

Wild stuff. You can see the bottom horizontal trusses bending when loaded. EMT is just too thin walled for serious structural applications
