I'm actually not wringing my hands over people choosing to use LLMs - I'm wringing my hands over the irresponsibility of the tech world in introducing and making available a technology whose existence will be responsible for a big chunk of the expected doubling of datacentre energy use over the next decade.

But the environmental aspects aren't even my main concern: my main concern is where that energy is coming from - and how the idea of Three Mile Island being restarted solely for Microsoft's benefit marks a huge shift (that no-one seems to have noticed) towards infrastructure that was previously at least nominally for public use being reserved for the use of a private corporation.

I'm also annoyed by the kleptocratic attitude towards training data, but I'll happily accept that reasonable minds may differ on that subject.

So while I don't use LLMs myself for ethical reasons, I don't have a problem with other people choosing to use them.
