I would argue that's not quite correct. You can absolutely transfer HTML files over gopher, but you're not going to be viewing it in the gopher program.It was very much designed to be what most people would be more familiar with in concept as an FTP server today, almost. Pretty much all you could view in app were plain text files. and no links between. Everything else was a directory of files to be downloaded.

Gemini is definitely a bit of an inbetween. It does allow for linking between documents, but otherwise keeps everything simple and small, much like Gopher did.

Impossible? gopher://gopherpedia.com:70/1
