Good examples of why it's not ready for significant use in production. They should have network sharding in sometime this year or next which will effectively leave contracts running on only as many nodes as they pay for. Tackling blockchain size issues will probably need some separate cleverness with distributed storage, though there are good precedents for implementing that.
