I would hazard a guess that there is an evolutionary lineage type of thing going on here: SV companies have borrowed both workforces and managerial skills from each from the Fairchild days, and as that became increasingly VC-driven it became almost systematic for newer companies to get extremely large in record time. Doing that puts the company on foundations that are fundamentally weak - there's no legacy to follow, just empty air. Hence the default model became a PT Barnum style hokum story, something that stirs up hearts and minds but will show them the egress once their wallets have been emptied.
