Certainly the Ethereum network has a lot of very strong developer activity and really interesting use cases. We want to build bridges to the ETH community and help support use cases that are impossible to run on the Ethereum chain.
Imagine you wanted to do some big data analytics on-chain. Today (and for the foreseeable future) it would be cost prohibitive to do such analysis on chain as the gas cost would be exuberant. Not to mention you would have to develop such a workflow in the Solidity or Vyper programming languages which are not well suited for the task. This kind of data-parallel and pipelined workflow is very well suited for the Internet Computer.
There are a lot of software developers in the world and we expect Dfinity to be a blockchain destination for any developer to build next generation decentralized applications.
