Creating a computer to find "the ultimate answer to life, the universe and everything", getting a cryptic answer and then creating an even bigger and more complicated computer to find the question is a pretty good satire of generative ai based chatbots of exponentially increasing model size.

Well, I am intrigued by the obvious analogies of Deep Thought and the prompt engineers (and their upcoming tools and their respective complexities) while on the other hand I already see the upcoming war between simple and dumb business interests on both sides that will try to make the fascinating und useful concept (which it is after all) consumable on one side while the other side will be ready to kill it if they don't get paid for it using/refrencing/quoting their pieces of work in its answers or "thinking"/modelling. Probably resulting in a cripled tool if politics won't visibly value educational gain over commercial interest.
Pain and joke too often come as closely bundled as within Adams's pointed work.
