This is the most similar question that I could find that already exists.

There are still HR and legal overhead costs involved if you have human operators.
I think part of the answer is also that the space of things low-wage workers can physically do remotely via teleoperation isn't that much larger than the space of things that can be fully automated but still much smaller than the space of things a local human can do. It's a fairly narrow band to exploit, IMO, and the labor cost arbitrage spread is rarely worth the complexity of the extra logistics, capital investment, and maintenance.
As @kave pointed out already, the right side being thicker would make it more clear that it's specifically a delta.
Embodied tasks just aren't an area where comparison makes much sense yet. What kind of perception tasks did you have in mind?
Does this "paradox" still hold in the era of recent multimodal AI? In particular, what are some things that are easy for humans but hard for AI, other than things requiring embodiment? What areas are human mechanical Turks still much better at? (I believe there are areas but pretty fuzzy about what they are.)
I really like the t-AGI concept for a specific task or benchmark but find it difficult to generalize since capabilities are not uniform. How do you classify an AGI that is 1-second AGI at some tasks but 1-day AGI at others (e.g. due to serial processing speed advantages)?
There is indeed the Myth of the flat Earth that is a misconception about the beliefs of scholars in the Middle Ages and some scholars certainly understood the concept of a spherical Earth since at least Eratosthenes. I'm referring to earlier history like ancient Egyptian, Chinese, and pre-Socratic Greek cosmologies. Admittedly, it's not a great example since most of the debates about it are lost to history, and such debates wouldn't involve the same kind of reasoning and evidential standards we use today.
Yes, clearly the less time the human has, the better Leela will do relatively. One thing to note though is that Lichess Elo isn't completely comparable across different time controls. If you look at the player leaderboard, you can see that the top scores for bullet are ~600 greater than for classical, so scores need to be interpreted in context.
Self-Elo inflation is a fair point to bring up and I don't have information on how well it translates.
"Artificial Intention" doesn't sound catchy at all to me, but that's just my opinion.
Personally, I prefer to think of the "Alignment Problem" more generally rather than "AI Alignment". Regardless of who has the most power (humans, AI, cyborgs, aliens, etc.) and who has superior ethics, conflict arises when participants in a system are not all aligned.
