I mean we've been using technology to solve long-standing problems in mathematics that no human had been able to do for years. Is Deep Blue sentient because it can beat any human at chess?
That's not removing the amazing ability of LLMs and the scale of this accomplishment, don't get me wrong - it's incredibly impressive that specialised models are now able to walk down pathways for creative problem solving - but I don't think that suggests a sentience or profoundness - rather it's just number-crunching at a astronomically larger scale.
