Personal experience? I don't care about benchmarks, nor LLMs' capability to solve puzzles. This is the first thing AI companies optimize their training for, which is misleading and practically false advertising. I care about how good LLMs are for helping me with specific tasks. Do they generate code that on the surface appears correct, yet on closer inspection has security and performance issues, is unnecessarily complex, often doesn't even compile, which takes me more time to troubleshoot and fix than if I were to write it myself? Do they explain concepts confidently while being wrong, which I have no way of knowing unless I'm a domain expert? Do they repeat all these issues even after careful re-prompting and with all the contextual information they would need? Does all this waste my time more than it helps? The answer is yes to all of the above. So while we can argue whether LLMs can think and reason, my personal experience tells me that they absolutely cannot, and that any similarity to what humans can do is nothing but an illusion.
