I would not say LLMs are products. It's still early adopters stage and it's going to be skewed on HN -- a large portion of people here evangelize the virtues of digging through an electronics store's parts bin to finish off a pcb they made in their garage then run an obscure version of linux on it for work. It's a lot of tech kludged together, not a product, not in the context of this article anyway. Same for the current state of LLMs. It's a tech waiting for a product to make it useful for the general population. For developers, Github's copilot is probably the closest, it bundles LLM tech to leverage their tech (github) creating a product you don't have to piecemeal together if you don't want too.
The internet was a tech that was first played with like we play with LLMs now. It was the web browser -- a product that leveraged a core tech -- that made it widely usable. Large parts of the population have no idea the internet is not their web browser (or now apps that access that web through a different interface).
I read a quote from the new Apple CEO on AI, that I think highlights the tech vs product separation and why Apple is where it is: 'We never think about shipping technology. We always think about 'how can we leverage technology to ship amazing products'

In the past, I worked in teams, building much more ambitious projects, and these rules would likely not apply.
