Serve Videos Instead of GIFs

Fragile narrow laggy asynchronous mismatched pipes kill productivity
Something I’ve been thinking about recently is how when I’ve worked on any kind of distributed system, including systems as simple as a web app with frontend and backend code, probably upwards of 80% of my time is spent on things I wouldn’t need to do if it weren’t distributed.
