> Seeing comments here saying “this problem is already solved”, “he is just bad at this” etc. feels bad. He has given a long time to this problem by now. He is trying to solve this to advance the field. And needless to say, he is a legend in computer engineering or w/e you call it.

This comment, with the exception of the random claim of "he is just bad at this", reads like a thinly veiled appeal to authority. I mean, you're complaining about people pointing out prior work, reviewing the approach, and benchmarking the output.

I'm not sure you are aware, but those items (bibliographical review, problem statement, proposal, comparison/benchmarks) are the very basic structure of an academic paper, which each and every single academic paper on any technical subject are required to present in order to be publishable.

I get that there must be a positive feedback element to it, but pay attention to your own claim: "He is trying to solve this to advance the field." How can you tell whether this really advances the field if you want to shield it from any review or comparison? Otherwise what's the point? To go on and claim that ${RANDOM_CELEB} parachuted into a field and succeeded at first try where all so-called researchers and experts failed?

Lastly, "he is just bad at this". You know who is bad at research topics? Researchers specialized on said topic. Their job is to literally figure out something they don't know. Why do you think someone who just started is any different?
