mariner,
Doesn’t H-m watch over the Torah (Ba’al Pe’eh as well) that we should be learning the right stuff? Weren’t there Gedolim in previous generations who spent much time with a lot of mesiras nefesh and Siyata D’Shmaya to preserve texts and make copies that are 100% accurate? I may be wrong but please clarify as you seem to be very knowledgeable (I don’t mean to be sarcastic, I’m seriously asking)
