See, I understand that you're trying to joke but the linked video explains how the use of the word dumber here doesn't make any sense. LLMs hold a lot of raw data and will get it wrong at a smaller percent when asked to recite it, but that doesn't make them smart in the way that we use the word smart. The same way that we don't call a hard drive smart.

They have a very limited ability to learn new ways of creating, understand context, create art outside of its constraints, understand satire outside of obvious situations, etc.

Ask an AI to write a poem that isn't in AABB rhyming format, haiku, or limerick, or ask it to draw a house that doesn't look like an AI drew it.

A human could do both of those in seconds as long as they understand what a poem is and what a house is. Both of which can be taught to any human.
