Dobbs Ferry, N.Y.: Voicer Eva Maciejewski’s letter representing the Foundation for Biomedical Research (FBR) is typical of the rhetoric issued by organizations that lobby for animal experimentation. Responding to my article on Neuralink’s unjustified use of monkeys to develop a brain-computer interface (“Elon Musk, monkeys and our human responsibility,” op-ed, March 14), it ignores the vast volume of work affirming the limitations of animals in achieving human cures.
