there are indeed dozens of incorrect papers which make neophyte errors. however, this one was written by a TCS Phd [from what I can tell] with a respectable number of published papers, some in TCS. I have studied this particular area of attack for many years, ie monotone circuit theory, & think it is one of the most plausible lines of attack on P vs NP, hence my playing
devils advocate for this proof so far. even if there are holes, which frankly, is the most probable case, it may either prove something new about monotone circuit theory, and/or raise awareness/interest in this particular direction of attack.
would like to see the opinion of experts who know about monotone circuit theory, which is a deep area with very many substantial results & think there are few who are really qualified to judge these results. even Phds in complexity theory may not be very familiar with monotone circuit proofs.... they are some of the most complex, arcane/abstruse, but even award-winning proofs in TCS.... (hence some of their plausibility in attack).... it seems possible to me the author has avoided all the basic traps and that only some other experts in the area can find the holes after careful study....
and note in the paper that there is a big difference between assuming statements that cannot be proven, and outright false statements. the author may actually have some pieces of the proof that cannot be proven as he thinks, but are not known to be false, and these can be turned into new substantial conjectures! that is the process of mathematical development....
