Sounds great, but your reasoning is not actually based in a solid scientific basis. It "kinda makes sense", sure, but is more anthropocentric than based on evidence. For the longest time people defined humans as "we're the only animals who can use tools; we're special". Nonsense, there are countless examples in the animal kingdom of tool use. "Oh but we're the only ones who can _make_ tools." Also nonsense. "Oh but only we can think ahead strategically!" Nonsense. "Only we have feelings". Nope. The whole "only we have anxiety and regret" is in the same ballpark. It's a claim without evidence. The connection with the neocortex is less clear than you made it sound, and the conclusion doesn't even hold up. Dolphins have a larger neocortical area. Not just by a bit, by over 50%! So let's keep the whole "humans are the only animals who ..." out of this which only serves to make us feel special. (And by extension is mainly used to exploit nature without regret. Whole religions are based on the concept of us being special and justifying atrocities against thousands of species.) Honestly it's absurd to think that only humans can experience flow. (Even disregarding that we don't seem to have a common definition of that state anyway, against which such claims could be tested.)
