VCs, and the Silicon Valley style culture in general, is a different investing culture than what Berkshire Hathaway is doing here. The underlying current of this discussion is which investing culture is better.
There's a lot of benefits to patiently waiting for an opportunity, rather than spending money as soon as it comes up. SV is surprisingly short-term in its thinking and culture. That's the lesson IMO for the past decade or two, SV is always about keeping up with your neighbors as opposed to thinking about the long term stuff that matters.
In the SV mindset, idle money is awful, you should have spent it on the latest-greatest recent whatever. 5 years ago that was maybe VR, 10 years ago maybe Internet of Things. Just 2 years ago it was cryptocurrency.
Guess what? If you spend your money on dumb things, you don't have money left over when the important revolutions happen. Patiently holding money is slower, but still valid form of investing.
