I believe you may be mixing up Paul Graham and Sam Altman. Easy to do because they both ran YC at different times, but WorldCoin is from Sam Altman and this tweet is from PG.
It's not 'easy' to mix up people who you are accusing of lying about having a friend with ALS for profit.
Worldcoin also has nothing to do with eye-tracking, unless you purposefully play with English words. The request is optimizing software & eye tracking. Eye tracking itself is a solved problem, maybe more is needed for disabilities but that is not Worldcoin.
And since the request is for the Bay Area to meet the friend with ALS, what was the game plan here, invite them in and trap them in his lair instead?
