Yes, building something new is a lot of effort. And? We have been doing it for a few thousand years, again and again and again. Cities were a lot of work. Irrigation was a lot of work. Farming was a lot of work. Castles were a lot of work. Roads. Aqueducts. International trade. And that was before the even more complex problems of modernity, after the industrial revolution. I don't understand the attitude behind such an argument. I would understand complaints if unwilling people were forced to contribute funds and/or time, but it's not like me or anyone else is forcing you to participate in this idea against your will.

I mean yeah sure but "I'm going to make a brain mesh so I can have an AR cartoon be my to-do buddy!" makes Knuth taking a multi-year detour from writing TAoCP to build TeX look like nothing.

I think that guy might have had one too many coffees if you know what I mean…
