Even a nobody likes me knows to take TAM estimates with a grain of salt, so I imagine experienced investors know too. I suspect if you added up all the TAM estimates for all the industries on Earth you'd get a number somewhere north of 10x the actual total value of the markets on Earth. I feel I'm being conservative; I really wanted to say 50x, but chickened out at the last minute before posting.
