It is a grift regardless of usefulness. "But it is useful" is hardly a justification for destroying the planet [0] [1] [2] without any viable efficient methods available today in training, fine-tuning and running it on every inference on tons of data centers.
All for so-called companies claiming to be 'AI companies' when they cannot even read or implement a technical paper and are just wrapping over someone elses API and immediately they are 'AI companies'. When it goes down they start crying over it 'not working'.
That is a confidence trick which is the definition of a grift and most replying here with excuses of "But it is useful" are likely to be underwater over their investments in inflated ChatGPT wrapper companies.
