He is likely a fraud. He did not invent the email; he wrote a program called EMAIL. Aside from that, ask this question. How is he still alive, or at least not threatened in any form, when he invented the almighty CytoSoIve, a system so powerful that would render Big Pharma's vaccine development method obsolete? People die for discovering better and cheaper treatments and I have not heard a thing from him in that matter. So he is likely one of them.
