Is it a native app, an Electron app, or a webapp? I don't even know because I refuse to get anywhere near it.

If either of the last two, it seems inevitable that their engineers would push as much of the compute server-side as possible to retain fidelity at the keystroke level.

We really should be doing a better job about demonstrating the distinctions between locally-run and -hosted tools, and cloud tools, for novices and laypeople.

Back when Facebook started pushing everything server-side it was a pretty obvious change if you were on a bad connection. When you'd type in a form on a bad connection it would often re-populate text that you had just deleted, or move the cursor around to unexpected places, presumably to match back up between their server-side caches and the local state. In the early days my adblock was interfering with this, too, which made the issue more apparent and caused some very strange behavior.
