[Jiucai], Let Me Tell You Why "Human Ideas" Are Not Infinite!
Today [Jiucai] posted claiming that "human ideas" are uncountable, meaning at least infinite. But this problem was solved long ago, yet is still being raised -- which shows the uneven level of those refuting Miss Chan. Quoted as follows:

"'Human ideas being infinite' does not equal 'human thoughts being infinite.' One could say 'human ideas' are uncountable, while 'human thoughts' are countable. I've roughly read your posts -- nothing remarkable. The reasoning ability of a middle schooler at best. You wouldn't even pass as one of Mathematics' students."
============
Even if this person doesn't know about quantum mechanics or that the interval for humans to produce thoughts can't be infinitely short, they should at least know that physiologically, the ability to produce ideas is the result of bioelectrical and other forms of energy operation. The time for a person to produce one idea is also impossible to be infinitely short. And based on the most basic common knowledge of modern physics, the time of the universe in which humans live is not infinitely long -- the universe also has an endpoint. Therefore the total of all human ideas is less than the universe's lifespan divided by the minimum time for a human to produce one idea. Anyone at an elementary school level would know that this formula means the total of all human ideas cannot possibly be infinite.
As for this person's passage, it only reveals their own level: "I've roughly read your posts -- nothing remarkable. The reasoning ability of a middle schooler at best. You wouldn't even pass as one of Mathematics' students." Of course, the "you" here doesn't refer to me but to Danye Hongfeng. But I only care about truth, not about who says what. Although Danye Hongfeng also has the mistaken idea that human thoughts are infinite, [Jiucai] saying Danye Hongfeng has "the reasoning ability of a middle schooler at best. You wouldn't even pass as one of Mathematics' students" is rather unfair. As for what level this person is -- I have no interest in knowing. The only thing that can be ascertained is that they don't even know human ideas are not infinite. That's enough!
