But everyone knows that bit, right. This was surely all Zuckerberg’s idea."
I had forgotten that, and no doubt he was aware of Lifelog given he had a pretty good tutor and attended college classes at Mercy while at Exeter; yet he had already created “Zucknet” (and later of course "Synapse").
You should really enjoy the movie more than most because the first 15 minutes (after it wades through some lawsuit exposition) ties Zucknet (without naming it) into FB's fast and furious scale-up, but the raison d'etre -- and I won't spoil it for you -- paints Zuckerberg as a fatally-flawed human being to his core and Sorkin just keeps driving that home during the length of the film. Schadenfreudic overdrive.
And even so, I'd rather make a business deal with Zuck, than Jack @ Twitter or the 2-headed dog at Google.
It was more than just awareness. It was a transfer of IP. DARPA was catching ethical flack, so they found the guy and kicked it to the private sector. Literally, the day LifeLog folded, the next day FB was incorporated.
Very eerie.
