ChatGPT isn't the only AI in the world (self driving trucks are one, many others constitute the simpler automated system used in factories that build the aluminium and the silicon and put it together to make a solar cell or a CPU); and even if ChatGPT was the only one, I don't accept that it's ability to create a business plan and investor pitch and convince humans to do that, is any less (at least in the ways that matter here) than an animal hunting for food, or a parasite using its host's assets for its own ends, or indeed most humans.

The most basic parasite still can make more parasites and grow to the extent its biology allows. AIs are more like tools, where their usefulness convinces the makers to make more tools. Is the potter's wheel a parasite, for convincing us Homo Sapiens to sit around gathering clay for thousands of years?

I really don't understand why you think that's a good point, sorry.

Even if I just say "yes it's a tool" (some AI clearly are regardless of whether they all are or any demonstrations of them being able to run economically interesting tasks without intervention), not clear how what you're saying connects with the ideas raised in the article?

"The Darwinian evolution of tools" is a statement that makes little sense because Darwin working with things that were alive - undesigned and capable of reproduction. There may be some similarities, but the processes behind each thing are separate enough to produce very different outcomes.
