> Abstracting away the ethical issues of your (elite) employment is a personal choice that is anything but objectively neutral.

Does this apply to doctors taking care a murderer, rapist, [insert felony here]?

Should this apply to the doctor of Yann LeCun?

Should these "personal choices" be valid, allowing the doctors to judge YOU, negating a cure?

You can extend 'doctor' to other professions too, like journalists.

PS: all those professions require to be objectively neutral.

Different professions can adopt different standard ethical frameworks. Healthcare is relatively unique in the code of ethics it chooses.

Nitpicking: If they build the weapons, they aren’t the researchers but the engineers.
