If an axon is what conveys the signal to the next synapse, does that mean that free nerve endings and their nerves are actually dendrites?

Hello Redditors :)

First post here, so please remove if it is not fitting.

I noticed (like many others did) that Picture generating AI's (Dalle-2 etc.) have problems with generating Text. It looks like it could be Text but doesnt make much sense most of the times. And i heard that AI processes Text in a different way than our brain does. So it doesnt really identify single letters but combinations of them. Which leads me to my question if the AI maybe does work similiar to our brain. I have a combination of closed-eye-hallucinations and Hyperphantasia. Which means that, when i lie in bed and close my eyes my mind starts generating pictures. Some random short scenes not connectet to each other. Can range from random faces, to made up movie scenes. If i focus on it i can influence my mind to what i want to see. So i tried to convince my brain to show me some Words or Text. But the same result happens, as if i would have asked an AI. It looks like text but it doesnt make sense. So the "idea" of text is present but it is not "real" latin letters. It reminded me a lot of what AI produces. So maybe the AI and the human brain have more in common than we think it has? I now, bold statement. It was just a random thought i had last night and i wanted to share it.

My friend at work and I had a very civil disagreement today. He tried convincing me that ADHD is a “made up” term. He made the argument that everyone has ADHD but it’s on a spectrum and each individual suffers from it differently. He said that impulsivity, racing thoughts, etc are all normal behaviors. I told him that having your brain run at 100000mph 24/7/365 is not normal and it’s mentally exhausting. What are some resources/research that can help prove his point wrong?
