I think the real shocker was the step change between 3 and 4, and the hope that another step change was soon to come. It's pretty telling that the latest batch of models was fine tuned for vibes and "empathy" rather than raw performance. They're not getting the next a-ha moment and want to focus their customers on unquantifiables.
It seems logical that this would negatively impact performance and, well, looks like it did.
Minitel was a text only early internet that popped up in France in the 80s. You connected to it through a small terminal connected to the phone line, and had access to various commercial services such as phone book, train booking etc...
Most of those services have been shut down a decade or two ago but some hobbyists are operating new services on the network.
