The point is that Bitcoin will improve, which is what MadGamer said, and I agree with that. In case it didn't improve (which is purely meant to be an example), MadGamer again rightly said that Ethereum and all other coins would become useless too by that logic. Don't take someone's post out of context, there is no need for that - read and acknowledge. Bitcoin has the first mover advantage, the most money circulating in its ecosystem, and the most secure and stable network. And don't look at market caps to think that Bitcoin is being surpassed by altcoins - market cap is a noob metric. Altcoins have their insane total supply to artificially boost their market cap. To add; Ripple and a few other altcoins have already surpassed Bitcoin's market cap, and that more than once.
