Seems unnecessary harsh. ChatGPT is a useful tool even if limited.
GNU grep also generates output ”with indifference to the truth”. Should I call grep a “bullshit generator” too?
An LLM operates a probabilistic process, and provides output which is statistically aligned with a model. Given an input sufficiently different from the training samples, the output is going to be wildly off of any intended result. There is no algorithm.
To have an algorithm, you need to have a concrete way to show than an output is the correct or optimal one.
An LLM is satisfied by providing any random output that passes some subjective "this-does-not-seem-to-be-a-hallucination" test.
GNU grep respects user arguments and input files to the dot. It is not probabilistic.
