My take is that devastating errata is just normal. Most of it is fixed silently and the end users never hear about it, but sometimes you're the customer that gets to find them. Right before I joined an embedded device team at Google, they brought up a new chip. Turns out... branch prediction was broken. It would mispredict a branch and execute the misprediction anyway. I imagine that was no fun to debug. But a workaround was fine and I'm sure subsequent customers never heard about it, and the devices worked fine for many years. One time I lived in an apartment that suffered from a variety of pests coming in. I expanding-foamed everything that looked like an entry point, the problem went away, and I stopped caring. However, I could still hear mice crawling around inside the walls late at night and decided just not to be bothered. This experience prepares one for embedded systems / microcontroller work ;)
