The current freeze in ETH transactions due to tx overload (too many transactions at the same time) indicates that ETH may not be structured in the best manner possible or, stated differently, does not entirely meet the needs of the public. I am not aware whether the maximum tx/s (transactions per second) in the ETH network can be increased easily but I understand there are other Blockchain 2.0 networks that support smart contracts (for example NEM (XEM) , Antshares and EOS) that boast scalability.
Perhaps those other networks are the next big thing in terms of decentralised hubs for smart contracts.
