Right $100 billion dumped all at once into VC would basically destroy the whole ecosystem. The saying is VC can't work when there is too much gasoline (capital) and not enough fire (talent/innovation). Despite the headline successes, most VC firms fail.
Their $100 billion tech fund is too big for the kind of deals that the typical VC invests in. It's pretty clear this is going to have various strategies. Lots of small investments in startups, buyouts like they did with ARM, and these minority stakes in public markets.
