They started a rewrite-from-scratch of all the apps, including mobile, using a custom in-house server-driven UI framework with a Kotlin DSL backing it, without so much as doing a proof of concept to find the tricky parts first. And by “started” I mean “committed to it” before anyone had so much as written a line of code to spike it out. Which, YMMV, but to me that seemed then, and still seems now, just wild.

Yeah. I hope they're at least doing it gradually. As in, rewrite a small component and have it run side by side with the rest of the original app, then rewrite another one and so on.

Oh.

Well, that sounds horrible, and will definitely take more years than rewriting it to React.

It's more FUN though!
