> tech companies are especially hard
Wiring harnesses from some entity in China I only have email contact with. Steel sheet metal fab across the country that likely needs months to get my order in. Surprise tariffs on my embedded boards due to Trump's trade war on China. Failures on some of these boards that leave the HDMI displaying, but frozen, and even a serial connection stops responding, so I have no way to diagnose it and suddenly a bunch of support incidents where the box needs to be shipped back.
The tech piece of this is by far the easiest bit of the operation. I guess what I'm asking is, "hard, compared to what?"
