You're Leaving Compute on the Table

August 1, 2026

There are six computers on my table right now.

My desk right now

All of them are awake. None of them are working. The hardest job any of them will do in the next hour is draw a spinner: waiting on a machine in Virginia to finish work whose every input is already sitting on this desk.

This desk is not unusual. Whoever your customers are, something like it is sitting in front of them. And for the most part, what’s on mine is more than capable of serving me.

Let’s look at what we have here:
