Vi and later editors added a lot of commands, but if you want to keep the spirit of ed(1) and bring it into a visual context, I’d say sam(1) is the true successor. It’s what Ken Thompson used after ed, and Brian Kernighan. There are some people who at least are interested in ed today, this book is good for example: https://www.tiltedwindmillpress.com/product/ed/
Is this real or a meme? Just curious…are there people still using ed? Is there a neoEd or would you just be reinventing vi at that point?
It is from the GNU humor page
