User claims to have made a website using chatgpt, putting programmers out of their jobs. However, it's revealed user knows next to nothing about making that website accessible for others, as revealed from the last line. User sent a local link (that works for their own computer only) to their friend (which naturally shouldn't work).
This sort of thing worked in the '90s. Many of the security restrictions in browsers these days means it doesn't consider the local file to be actually local, and you have to host from some kind of server. There are mini servers that are trivial to spin up, like SimpleHTTPServer on Python.
The joke is it's an iMessage chat and they are sending a Windows path which doesn't make sense for iOS or Mac, the only two operating systems that support iMessage.
