Unless you can run the LLM locally, on a computer you own, you are now completely dependent on a remote centralized system to do your work. Whoever controls that system can arbitrarily raise the prices, subtly manipulate the outputs, store and do anything they want with the inputs, or even suddenly cease to operate. And since, according to this article, only the latest and greatest LLM is acceptable (and I've seen that exact same argument six months ago), running locally is not viable (I've seen, in a recent discussion, someone mention a home server with something like 384G of RAM just to run one LLM locally).
To those of us who like Free Software because of the freedom it gives us, this is a severe regression.
The point being made here is that a developer that can only do their primary job of coding via a hosted LLM is entirely dependent on a third party.
I mostly write JS today and it either runs in browsers (dependencies) or a host like AAwS (dependencies). I use VS Codium and a handful of plugins (dependencies).
These all help me work efficiently when I'm coding, or help me avoid infrastructure issues that I don't want to deal with. Any one part is replaceable though, and more importantly any one part isn't responsible for doing my entire job of creating and shipping code.
