Reinventing the wheel, but every time different. The author shares its experience.
Consider standards for it: they are powerful.

Some wheels I see that I think could use some new takes but which I don’t have the time/energy to do myself:

• Web browsers - probably the most significant. The browser market is essentially a monopoly right now. And Firefox is pretty much the only alternative option, somewhat of a monopoly in itself. We need to have many independent browser projects going on, not just an alternative.
• Higher education - this is probably too big a project for any one person, but I think there’s a lot of ground that needs new work and reevaluating in the world’s current higher education system.
• Task management - there are a lot of task management systems out there, but I think there’s still definitely room for more. I’m personally beginning to settle on a hybrid analog/digital task management system I’m designing myself.
