Ethereum is super overrated.
Ethereum is a platform that other applications and services can use, primarily through smart contracts. Ethereum has been very aggressive with it's development and has not done a great job of creating a secure environment (see MultiSig contract bug). Eth also doesn't really scale well (see Cryptokitties). Ethereum is also too centralized and have set a precedent that it is not immutable (see DAO hack), which is a fairly large problem for a trustless cryptocurrency system. Ethereum is also probably not centralized enough in that real business enterprises (not startups but established companies) are not going to want to build on top of it.
The larger problem with these smart contracts is that they are very difficult to secure, and many people attempting to write them write it in a way that gets exploited. Devs have too much freedom in smart contracts, and can too easily hang themselves with imperfect code.
So what is ether, really? If Ethereum is a platform for other applications to ride on top of using smart contracts, than Ether is just a way to fund smart contracts that don't really work all that well.
