I'm bored and don't know where exactly to put this, so I'll put it here. Mainly it concerns the BIP, but that's what a few Oligarchs seem to be after anyway.
Me and a few other people were talking, and it seems to us that the BIP since it can go into any RSI it wants, probably was the thing that gave The Ones their powers in the Matrix and the Real. Through the cycle that the Machines had(have?), they have the Prophecy that drives a portion of Zion to find the One. But, to make sure to attempt to keep The One/the rest of Zion from getting outside it's parameters, they have the Biological Interface Program in the One since they were a bluepill. Because the One's actions are so significant given their powers, coupled with the Machines' actions in the real and in The Matrix, the BIP in the One keeps Zion in check for a large period of time until the reset occurs.
This also brought up the memory of Halborn saying in a Crit something along the lines of "If only
he hadn't of taken the other one." That probably means that there's not one but
two Biological Interface Programs. Thinking on why, the BIP seems to be very random and not directly controllable by the Machines. So, they needed something to counteract the BIP, and what better way than with another one? So throughout every version of the Matrix, the two BIPs have kept each other in check so that neither Zion prospers nor the Machines lose their seat of power.
So the Oligarchs want it for whatever reasons. They've said themselves that they've lived for much longer than a typical human lifespanm, through whatever way they do it (BIP or some other help from the Machines perhaps). Halborn was very interested while searching for the BIP in the powers that The One had, and did not know that Neo could shut down sentinels in the Real; that the Machines had told him of Neo's powers but not fully. So, people are probably after the BIP because they think that if they had it that they could have the powers of The One, maybe even greater with their understanding of the BIP.
On another observational note, the BIP seems to have some similar properties as a system program dubbed by "The Joker" so-to-speak: "
Bandersnatch". It can multiply seemingly an endless amount of times. It's possible that the BIP can examine another program and obtain the same powers/properties as the program, sort of assimilating them without consuming them; or it's possible the Machines/The Oracle programmed the BIP(s) with that ability.
