I would be grateful, if someone familiar with the situation could say a word about this.
As for the proof in question - I'm not sure the author himself can firmly state he understands every detail of what he presented. In a way it's amusing that people who already enjoy a certain level of recognition outside the field are now using it to find (via shiny websites) reviewers for proofs they have worked out as a hobby using Chat GPT and the like.
What we definitely need is more recognition for those who possess the competence and energy to assess the correctness and relevance of such "results".
