Ha, this certainly places it in “damned if you do, damned if you don’t” territory. If there’s one thing people on this forum keep saying when a new system is proposed or floated, it’s “You need to make a killer app with that system to show people what it can do and get people into it!” Poor Linus makes multiple killer apps and the result is scariness
