To be honest, for a lot of people this is a good decision. AI is already better at cognition and research than a fairly good chunk of the population. If they start thinking at a reasonable level, believing less obvious lies with the help of AI, we all will benefit. Obviously Grok isn't the best choice but still probably better than what a lot of them would come up with on their own.

AI doesn’t have cognition and it doesn’t do research, it’s a piece of software that cannot think or learn.

Yeah I've heard this before. People who are confident about things they know nothing about say it. I worked for the largest AI researcher in the world and work with this technology every day for my current job. I talk to experts all the time about it. I've never heard an expert in the field make any characterisation roughly like that with any confidence. Great example of the dunning-kruger effect. The end result is that AI's produce more accurate answers than the bottom half of humans the vast majority of the time. Feel free to argue your uninformed theories about how they work all you want, seeing as no one knows it well nor does anyone really understand all the mechanisms that make our brains think. The mechanism doesn't really matter if the results are there. I know a few MAGAts who would greatly benefit from outsourcing their brains to AI. They would make far better decisions with their lives.
