Shitcoins, despite their multitude, are inconsequential
I don't quite like such statement, far too broad IMHO.
You don't like a coin, call it shitcoin all you want. But the fact is that inside all those new coins, most of them have low technological value or usecases but SOME OF THEM have something unique. Be it usecases like ETH and ICO or technological differences like Monero or GRIN. It's easy to call everything not bitcoin shitcoin but it's unfair and innacurate. There is value everywhere including in the altcoins
I understand your pain
And to alleviate it somehow, let me tell you that I in no case consider all altcoins shitcoins. In fact, far from that. If that was your first thought, you can now safely abandon it. I don't know what ICO is unless you refer to Initial Coin Offering, of course (though in that case it is not clear why do you mention it after Ethereum), but to make things clear, I don't consider Ethereum a shitcoin, either. While it is certainly easy to call everything not bitcoin a shitcoin, I'm far from that as well. Quite the contrary, some altcoins are quite useful and can even be Bitcoin's proxies as a means of payment for daily necessities (for example, Litecoin)
