Well if the AGI field had real proof that AGI was possible sure. The problem is the proof for AGI is in the doing and the fact that you think its possible is baseless belief. Just because a person can do it does not mean a computer can.

Reduction to QED

The question of AGI is an open question and there is no way silence the opposition logically until and AGI is created, something you won't be doing.

Aside: I know the Quantum Physics Sequence was sort of about this, and the inside vs. outside view argument is closely related, but I wouldn't mind seeing more discussion of the specific phenomenon of demanding experimental evidence while ignoring rational argument. Also, this is at least the second time I've seen someone arguing against AGI, not on the object level or a standard meta level, but by saying what sounds like I won't believe you until you can convince everyone else. What does it matter that the opposition can't be silenced, except insofar as the opposition has good arguments?
