Kabamur is the one most likely to be legit in my book. He has his "twitter persona" moments too, as almost everyone there.
The twitter infighting (kabamur vs sather vs mj12 vs michele etc.) and the attempts by shills to spread it here ("X is legit and Y is disinfo! No, Y is legit and X is disinfo!") is a prime example of shill kayfabe and a timesink from research. Be wise and remind newfags of their old playbook.
This speech by POTUS is very telling of 40k+. It's wrapped up in the "young innovators" plausible deniability, but the words say it all. High tech and unbelievable advancements are just around the corner.
