Lumon’s Ultimate Goal

Just a theory but I think that Lumon’s ultimate goal is to reincarnate all the previous Eagan leaders. The macrodata that our beloved team is refining is the immense macrodata stored in the brains of potential human hosts to make them more compatible with each individual Eagan that will eventually be downloaded into them. They need to refine out all of the excess “data” that makes up their personality in order to make the process work, otherwise when they merged the two personalities, there would be re-integration like side effects.

To add to this theory, Mark S might be the chosen host for the reincarnation of Kier Eagan himself, which is what makes him so important to Lumon and what makes them give into his demands when push comes to shove (like bringing the rest of his team back). The board is just the “brains in a vat” of all the former Eagan heads, which is why we never see or hear from them directly and why Kier’s voice lines all sound like they are coming through a weird text-to-speech recording. Helena’s dad also made that weird comment about the time of his “revolving”, which could represent either the time when he will eventually join the brain in a vat board or the time when he is brought back to life after his host is found and refined.

Lastly, the idea of reincarnating the dead might be what drives Ms. Cobel—perfecting the technology so that she can bring back her mom in a new host.
