Sorry if I sound a bit arrogant or stupid but I really care about this idea, it's like a child, you know? Feel free to give any advice or whatsoever.
Anyone who replies, perhaps suggesting a more private discussion, could be, well, anyone. The odds that someone who's reputable in a way you can verify easily taking a keen enough interest to bother with all that are probably relatively low. So it's no different from throwing it out on Reddit, except the audience is a bit narrower and smaller.
What are the odds that someone is trolling HN looking to engage in identity fraud or a con scheme to get their hands on your prototype so they could then do a lot of hard work to implement it? I can't really weigh that! It's a lot of work for about as much certainty as you have that it'll pay off. On the other hand, it's a crime of opportunity that does align with the skillset...

You could build a python scraper that aggregates all the posts like this already on reddit, feed it to an ai, and then you can generate infinite pitch decks- then get a UX/UI designer it shouldn't take a lot to build an MVP or just a mock up with Figma.
