While interesting, the ethical implications are what got me interested in the extended mind theory. If I cut out a piece of someone's brain, and that turned them into a lesser functioning human being, then what I did would be considered unethical by most people's ethical frameworks. But what if I took away your paper and pencil, or computer, or abacus? Is that unethical? This has tangible effects on schools that lack funding for tools, or those imprisoned without access to books and writing material.
