Any system complex enough to be useful has to be embedded in an ever more complex system. The age of mobile phone internet rests on the shoulders of an immense and enormously complex supply chain.
LLMs are capturing low entropy from data online and distilling it for you while producing a shitton of entropy on the backend. All the water and energy dissipated at data centers, all the supply chains involved in building GPUs at the rate we are building. There will be no magical moment when it's gonna yield more low entropy than what we put in on the other side as training data, electricity and clean water.
When companies sell ideas like 'AGI' or 'self driving cars' they are essentially promising you can do away with the complexity surrounding a complex solution. They are promising they can deliver low entropy on a tap without paying for it in increased entropy elsewhere. It's physically impossible.
You want human intelligence to do work, you need to deal with all the complexities of psychology, economics and politics. You want complex machines to do autonomous work, you need an army of people behind it. What AGI promises is, you can replace the army of people with another more complex machine. It's a big bald faced lie. You can't do away with the complexity. Someone will have to handle it.
