They can find issues now though. Will they also find non issues due to missing context or not understanding the whole operational picture, well yes, but you can usually filter those ones out quickly. While i wish we had QA back and it be a norm again in software engineering as a whole, without it I'm happy to have something look for ways my code will break in unexpected manners that testers previously handled. Is it the same as having someone sit their and try and break your shit for the sole purpose of finding a spot where something will go completely off the rails, no its not but with a lack of true QA and rushed timelines that leave little room for quality QA yourself.

Especially considering I can do this without making users of my code the guinea pigs in lieu of an actual QA department. Sometimes you have to make the best of a shitty situation and honestly its an improvement over no QA which has been a norm for a while now so I'll take the small wins where I can
