The thing that was most disillusioning for me here was SVB -- failure to apply basic principles of banking (i.e. they never really had a plan for central bank interest rates to change more than +-1%). Not just that the VC types running a bank weren't able to do so, but that such a large number of tech companies held all their cash on hand in a bank account (and didn't deposit anything in another bank, or a money-market fund/t-bills).
