I am often skeptical of innovations in cryptography, could any crypto experts snuff this one out? The OP claims it is superior to RSA but hasn't necessarily verified these claims.
If one accepts that a cryptography expert would publish either a peer-reviewed academic paper or a comprehensive article instead of a twitter post, then one may conclude OP is not a cryptography expert. Additionally, the focus on length ahem and no other metrics is a common symptom of non-experts (I posit an 8MB key is not practical). The moral of this story is, it is wonderful and encouraging to have a new idea in any domain, but the next step is to ask yourself (or a few select individuals), "how do I evaluate my idea?" _Everything_ you will learn while answering that question will be valuable. Posting to twitter almost never is.
