Saying it's "an LLM" doesn't change the impact. GPT4 is an LLM, and so are many others ranging from toy quality to GPT3.5. It is very clear GPT4 is much better. If there is another jump like GPT4 , whether it is LLM or not, it's impact will be huge.
Would you be "comforted" that this mega-genius is worse at arithmetic than you are and doesn't remember what it did yesterday?
Probably not. You might well be worried that this weird psychopath is going to get a medical license and cut the wrong number of fingers off of a whole bunch of patients.
also it knows when to use a calculator if it has access to one so it's not a big deal
