Meaningful AI criticism no longer comes from armchair philosophy; it requires deep mathematical and engineering proofs. AIs like GPT-3 can generate criticism that is just as good, if not better, than human critics who lack a technical understanding of how the models are built.

Unlike scientific fields that build on previous discoveries, philosophy progresses cyclically. Each new generation must start fresh, grappling with the same fundamental questions of life and knowledge. This is why ancient ideas like Epicureanism reappear in modern forms like utilitarianism, as they address timeless human intuitions.

A key measure of philosophy's historical success isn't solving its own problems, but rather birthing new academic fields. Disciplines like mathematics, physics, economics, and psychology all originated as branches of philosophical inquiry before developing into their own distinct areas of study, a point Bertrand Russell made.

Unlike science, which aims for linear progress, philosophy's value lies in its contribution to human understanding, similar to art. Judging philosophy by a standard of "progress" is a category error; a great philosophical work, like a great play, remains valuable regardless of what comes after.

Analytic philosophy's attempt to emulate science—seeking "local results" and linear "progress"—is a fundamental category error. Unlike science, philosophy doesn't accumulate objective results. This model encourages technical, sterile exercises and devalues historical context and literary style, which are essential to the discipline.

Critics argue moral thought experiments are too unrealistic to be useful. However, their artificiality is a deliberate design choice. By stripping away real-world complexities and extraneous factors, philosophers can focus on whether a single, specific variable is the one making a moral difference in our judgment.

The classic thought experiment is deemed ineffective because it doesn't genuinely probe a moral intuition. Instead, it merely restates the argument's premise—that people are only moral for instrumental reasons—packaging a conclusion as a speculative scenario.

Michael Shermer highlights that reason isn't purely for objective truth-seeking. It also evolved to help us persuade others and defend our group's beliefs. Often, our minds act more like lawyers defending a client (our beliefs) than scientists searching for objective reality.

Engaging with people who argue from flawed premises is rarely productive. Sam Harris calls this "asymmetric warfare" because it is far easier to make a confusing mess with bad arguments than it is to clean it up with good ones, making the debate a net negative for audience understanding.
