Your proposal lists reasons for why your platform should exist, but it doesn't list any reason why a user would want to use it. Who are you serving? What should they want to sign up?
Most of what we use now is profit seeking, everything is built to fuel an addiction and increase screen time as opposed to being a utility that benefits you. As a user the idea is that you'd actually be free from that. The technology would work for you, not the other way around.
I'd like to work on one that maybe uses ai/ml to basically learn the stuff that I'm interested in, and then rank it by most interesting - again based on previous interests. Essentially clone myself on the app, and then only see the stuff that is probably worth seeing the most.
