Are they? Every foundation model release includes benchmarks with different levels of performance in different task domains. I don't think I've seen any model advertised by its creating org as either perfect or even equally competent across all domains.

People like Zuckerberg go around claiming most of their code will be written by AI starting sometime this year. Other companies are hearing that and using it as a reason(or false cover) for layoffs. The reality is LLMs still have a way to go before replacing experienced devs and even when they start getting there there will be a period of time where we’re learning what we can and can’t trust them with and how to use them effectively and responsibly. Feels like at least a few years from now, but the marketing says it’s now.
