What's the end game of altcoins?

Every cycle, new buzzwords come out. Most of the time, they start with “Bitcoin is slow, useless, can’t do backflips, can’t buy cat pictures, can't tokenized my wife's boyfriend house, or launch a memecoin for my pet lizard.” Then every cycle, new altcoins claim to be faster, better, more secure, or more decentralized than the last cycle of alts.

Okay, so what’s the endgame? When can you finally say, “This is the coin, this will replace Bitcoin - it's like buying Bitcoin at $1” if in the next cycle someone will just make another one that’s supposedly “better”? It’s the same loop of hype and promises.
