No, the correct analogy is one where the major LLM providers are selling cars intended for use on US interstate highways and other public-access roads, but have designed and built these cars with the very latest in 1940's safety systems and construction. Featuring innovations such as "Our rigid solid steel construction means the occupant is the crumple zone!", "You'll love the crushed heart and jaw our steering column delivers!", and "Your passengers will enjoy picking glass out of their faces for the rest of their lives when they're ejected from the cabin's open bench seating through the plate glass windshield!", it's a car that will be sure to wow the market.

Well... it would wow the market, except that -in the US, at least- it's illegal to sell a new car intended for use on public roads that ignores the last seventy five+ years of automobile safety lessons we've painfully learned.

"Differentiate between data you know comes from sources you control, data you know you have thoroughly sanitized, and unsanitized data that comes from an untrusted source, or else attackers will gain control of your system." is something that you can't get a CS degree without understanding, and can't be in the industry for more than a few years without encountering repeatedly. We're not talking about designing new cryptosystems... we're talking about "Don't blindly trust everything you're told by strangers.". You don't even need a CS degree to understand that rule.
