Actually, I'd wager it isn't even about the money. Ffor his reality it's a vague abstract number. He never really has to worry about running out and can live as extravagant of a lifestyle he wants. To the extent the details matter, it's more of a 'high score' than anything that actually materially impacts his life.

The real punch in the gut is that he has gone his entire life with the masses either kissing his ass and worshipping him as the greatest tech guy ever, or people who just don't care about him either way. He of course earned some personal vitriol from people who knew him personally, maybe more than the average but he always felt vindicated by his adoring masses.

Since every random person that he actually ever heard express any opinion put him on the highest of pedastals, then surely every one will be relieved if he forced himself and his ideas over their lives? Suddenly he has to face the judgement of so many mililon people that were previously content to largely ignore the hell out of him. This is probably really hard to cope with after 50 years of unrelenting ass-kissing.
