Ethereum is getting bashed a lot for this reason, but at the same time this is new technology, and it's going to require a lot of iterations to improve. Failure is the first step.

I appreciate all the developers building applications such as CryptoKitties, in the same way that I appreciate Steem.

In the end, I really care about Blockchain taking off. I understand your frustration though, for this reason I'd probably not attempt to use CryptoKitties either. Thanks for the heads up :)
