The claim in the article seems wrong -."..ICP is a replacement for one of the building blocks of the internet made a protocol called TCP /IP"

Most likely the article writer is not a developer but a marketer.

As a developer I know that any type of communication builds on the top of TCP /IP. This is what we use in our Decentralized web project.

And, instead of comparing with Ethereum on speed we have our independent/owned Ethereum instance.
