Exactly. Somebody running a company can't be an expert in everything. But they can be a good judge of people and have a wide enough network that they can get recommendations from people they trust.
A few of those trusted technologists will make a fine hiring/oversight committee. You won't need a ton of their time, so you can pay very generously for the insurance they provide.
Ultimately, if you cannot identify critical staff and don’t know anyone who can, you’re screwed anyway.
