I used to PL and I think that is one of the dumbest things I've heard. It would have made more sense to say that quitting early is teaching youself to quit! You should believe you are capable of another rep. If you don't make it, big deal. I'm not saying PLers should train to failure. I always cycled myself. I'm just saying that sometimes it happens, and you shouldn't be thinking "oh no, I don't think I can get another rep" in the middle of a set, and put it away out of fear of failing.

You wouldn't happen to be James "Traps" Ayers would you?
Seriously though, I think we have to be careful in how we interpret what Dr. Squat meant by that remark.
Personally, I took it to mean something like this...
In lifting, powerlifting in particular, you can gain without training to failure, right?
I might like failure training a lot myself, but I readily admit that you can achieve progressive overload without it. And failure is often thought to be very hard on the CNS. There are ways around that in a bodybuilding routine (DC, cycling exercises and periods of hard training with light stuff), but in powerlifting, training to failure on the same exercises
again and again would quickly lead to CNS burn-out, depending on the specifics of the routine of course.
Therefore, in a
sense, training to failure IS "training to fail"--fail is in
failing to progress--because you'll burn out too quickly doing it.
IF that's what Dr. Squat meant, I agree with him. We really need a context for that quote to say either way, though I do suspect your interpretation is probably closer to what he meant.
I agree with you in that case...
some failure training isn't going to make someone magically weaker than they should be.
It'd take a lot to measurably derail your strength.
