I don't know if these things work or not but the premise that improving people's abilities is somehow unethical is dangerous.

One could argue that giving good education to students gives them an unfair advantage to those without such an education. Does this mean that education is unethical?

Improving people's mental ability, whether through drugs or education, improves all of our lives. To win at being higher functioning and making better choices is not just a win for the individual but for the society at large. Those people can go on to improve the live of others and grow our collective economy. It's not zero sum as athletics can be thought of.

As an aside - if these improvements make us less human, then I don't see why modern medicine doesn't also make us less human. Do we define human purely as a certain cognitive ability?
