There was some Round Earther who said that the burden of proof about whether or not something is Turing-complete definitely lies on one who claims that it is, because, for example, HTML is very complicated, yet it isn't Turing-complete. But he said that the rest of my argument seemed legit.
HTML is a scripting language, not a programming language. This is a case where greater complexity is needed to intentionally limit flexibility (for example, to protect the browser) -- from an evolutionary perspective, this is kind of nonsense (why would a brain evolve to be less flexible and capable of learning and interacting with the environment and expend more effort to do so?).
Scripting languages have to be programmed to begin with, as such Occam's razor favors programming over scripting. It's simpler, more primitive, AND more flexible. In order to have a high level scripting language, much more low level programming is required than to create something like a mind.
People make assertions about animals being driven solely by instincts, but this again is a misunderstanding. Yes, evolution has to input some basic rules (like the rules in the game of life), but it's much simpler to evolve those basic rules and then let the system run itself with those parameters to create complex and appropriate behavior than to evolve a huge set of detailed applicable rules that control behavior directly with any usefulness.
We've even found this true in engineering, where adaptive neural networks and evolving systems are just much easier than trying to work out all of the rules something would have to use to program it directly.
This is a case where it's more complicated evolutionary to make a complex system that isn't intelligent than one that is, and much slower to create behavioral changes (which means extinction for most animals). With intelligence, unlike instinct, it changes with every stimulus instead of only every generation.
When we look at animal behavior, the simpler assumption is that it is learned rather than innate/instinct, because we understand how learning works and how primitive the process ultimately is (even insects engage in it). We're talking about an adaptive neural network: all evolution has to do is set a few simple rules, and it creates emergent behavior based on interaction with the environment. This is what Occam's razor prefers, and the burden of proof lies on those who claim otherwise.
Please feel free to invite that normal-actual-shape-of-the-Earth-accepter here to discuss it.

Then there was some Flat Earther who claimed that the human brain is something more than Turing-complete and used quantum mechanics to explain how it works. Then said Round Earther pointed out that quantum mechanics doesn't open the door to the hyper-computation, that it's not to be expected that quantum computers would be better at walking and recognizing things around themselves, and that using quantum mechanics to explain consciousness is usually considered pseudoscience.
Right.
Quantum is usually just a pseudoscience buzzword today.
A. Dragons exist, and your friend has been on one.
B. Your friend is a liar and dragons exist. Why did he lie?
C. Your friend is telling the truth as far as he knows, but is delusional and has not really been on a dragon, and dragons do exist.
D. Your friend is a liar and dragons do not exist. Why did he lie? How is this massive conspiracy theory to make people believe in dragons maintained? Why would anybody do this? Why don't dragons exist? How is all alchemy wrong?
E. Your friend is telling the truth as far as he knows, is delusional and has not been on a dragon, and dragons don't exist. etc.
There was no massive conspiracy to convince people of dragons, they were just ignorant. There was no science supporting a theory that required dragons to be possible. The Alchemy (if there was even an alchemic theory of dragons) was wrong because it was pseudoscience. The esoteric claims of alchemy never generated any results; unlike modern engineering which you see the products of all the time (the same theories that make airplanes work make a fan or a car work). Ultimately, Alchemy dropped those supernatural aspects and evolved into chemistry by retaining only what was based on evidence.

Not really. There were no widespread claims of having seen or ridden dragons. That was considered extraordinary, although people may have accepted it happened sometimes. At best, you might put that in the category of, "I had lunch with Obama". Possible, yes, but a pretty extraordinary claim.
Compare the number of people who claim to have had lunch with Obama, and those who actually have; which is a larger number? This would tell you something about the chance of somebody lying.
Meanwhile, the number of people riding airplanes is huge, and the number of people claiming to have done so is probably only slightly larger than the number who have (the number of people riding airplanes and then forgetting about it may be larger than the number who lie about it).
Only when a claim is pretty extraordinary is it more reasonable to consider that it may be a lie and require more evidence (unless you just know your friend is a compulsive liar). If something has less than a 10% or so chance of being true, I may start wanting to see evidence and become willing to imply I don't believe somebody. If I require evidence for something that has a 50% chance of being true and call somebody a liar on those grounds, I'm probably being an asshole (unless the person has a very strong motive to lie, like it was a coin toss the person claimed to have won; I may want to see the coin).

Not at all. See above: option D is now equally or more viable compared to A, because a number of necessary assumptions have been stricken.

The conspiracy in itself is a huge assumption, and pretty much mathematically impossible.
