I didn't say if "adoption doesn't take off" I said "fully overtakes node". Should no other browser be invested in because Chrome has the largest market share?

I didn't say if "adoption doesn't take off" I said "fully overtakes node". Should no other browser be invested in because Chrome has the largest market share? Should no-one ever invest in a competing product? I believe it is up to his investors what the expected growth rate and market share is.
