No, philosopher, he wants to say what I’ve been saying a long time. qwerty is talking garbage and arguing from a standpoint that is against that of lomdei Torah for centuries. All his invective is pointless if he doesn’t know how a 15 year-old yeshivah bochur learns, and it’s clear that he doesn’t.
As to you having listened to many shiurim on Yaakov Avinu lo meis, and none having said that he is alive… so what? Rashi says it, the Rif on Ein Yaakov says it, the Or Hachayim says it, the Ramban defends it against your questions from pesukim – isn’t that enough for you?
If any of your aforementioned talmidei chachomim said that Rashi is wrong (c”v) I would call them apikorsim, or at the very least huge am haratzim, but I am 100% sure they did NOT say that. You have to realize that aggadata is a prime source for derashos and shmuessen which are designed to attract and uplift an audience. Citing other meforshim who explain the statement in a way which is more suitable for a derashah is par for the course, and I would do the same if I was giving a non-lomdish talk. Citing Rashi et al doesn’t give you much opening for a derashah. That doesn’t mean chas veShalom that they reject Rashi! Ask them.
There’s another point here which is very very important. Were you to reject Rashi on the basis that the Maharsha or some other well-accepted meforash does, you would be wrong in doing so because אלו ואלו דברי אלקים חיים, but it would be little more than a mistake. If you reject Rashi because in your opinion what he says doesn’t make sense (c”v), which is what you have implied by incessantly referring to the impossibility of him breating etc underground, then you are rejecting him based on YOUR comprehension. That is unacceptable in Torah learning, and close, if not equal, to apikorsus.
