That definitely doesn't line up with what I've seen, failurewise. One of my ESP-32s has been running pretty much continuously for 3 years without any trouble. And in the past I've had no trouble running multiple for months at a time. The only failures I've had, across maybe 4 different manufacturers, happened when I did something dumb and unintentionally fried a board.
