Sure, it's a sign that we don't "understand this stuff properly", but you can say the same about human brains. Is it a red flag that we use language to communicate with each other instead of manipulating nerve impulses directly?
We have no choice but to have and use our brains, not so with LLMs. We don’t have to start building core technologies off of fundamentally flawed models.
When self-driving cars were first coming out a professor of mine said "They only have to be as a good as humans." It took a while but now i can say why that's insufficient: human errors are corrected by discipline and justice. Corporations dissipate responsibility by design. When self-driving cars kill, no one goes to jail. Corporate fines are notoriously ineffective, just a cost of doing business.
And even without the legal power, most people do try to drive well enough to bit injure each other which is a different calculus from prematurely taking products to market for financial gain.
