I remember the old ADSL modems where effectively winmodems. I had to keep a Windows ME machine as my household router until the point the community had reversed engineered them enough to get them working on Linux.
At least they where usb based rather than some random card. I think the whole driver could work in user space.
I thought CoPilot was just a rebagged ChatGPT anyway?
It’s a silly experiment anyway, there are very good AI chess grandmasters but they were actually trained to play chess, not predict the next word in a text.
