Here's an odd guess, in keeping with the number/alphabet code Q seems to be fond of at times.
[19]= 1 (A), 9 (I)
AI = Artificial Intelligence.
AI = related to Vault 7 information regarding "Rainmaker" and "Keystone". See Smileyface's video that I've reposted TWICE and nobody has yet to comment on.
IMPORTANT video. Get rid of certain select individuals (CEOs) and AI ceases to exist.
Plausible?
My comment (working from memory) is I wasn't impressed because the hacking tools were conflated (I briefly studied the material at vault 7, shortly after it was exposed), and the video neglects to explore the context of "keystone" in the Q-drops.
I still thought it was a valuable video, to the extent it prompts people to study the underlying materials.
I’m sure it is nothing but remember when Farrakhan went on about 19? It has been ages ago.
“When you have a 9 you have a womb that is pregnant,” Farrakhan explained, “and when you have a 1 standing by the 9, it means that there is something secret that has to be unfolded.”
“Religious text, especially the Bible and the Koran, are believed by some groups to contain hidden messages that can be broken through codes based on numbers. This is the concept behind a process called gematria. Muslim Louis Farrakhan supports the mystique role of numbers in his faith, giving particular attention to the importance of the number 19.”
