I don’t think all papers are pointless but it’s been shown that many are not reproducible, so those are worthless and pointless. There was that guy a few months ago who tried to reproduce the results of 130 papers on financial forecasting (using ML and other such techniques) and found none of them could be reproduced and most were p-hacked or contained obvious flaws like leaking results data into the training data. An academic friend of mine who works in brain computer interfacing also says that a large number of papers he reviews are borderline or even outright fraudulent but many get published anyway because other reviewers let them through.

So I definitely wouldn’t dismiss all papers as pointless, but there certainly is a large percentage that are, enough that you can’t simply accept a published papers results without reproducing it yourself.
