It is actually incredible how they managed to find an even more unscientific definition than "can perform a majority of economically useful tasks." At least that definition requires a little thought to recognize it has problems[1]. $100bn in profits is just cartoonishly dumb, like you asked a high schooler to come up with a definition.

[1] If a computer can perform the task its economic usefulness drops to near zero, and new economically useful tasks which computers can't do will take its place.
