Review on Ethereum by Nathanael Ries

Because there is so much risk in developing the technology for scaling that literally does not exist in the world right now, and due to the nature of the blockchain making these upgrades immutable, development time by necessity must be slow so that testing can be thorough and bugs in the software are discovered. Due to this development slowness, other less scrupulous blockchains have claimed to "solve scaling". Unfortunately these blockchains that have "solved scaling" have all used centralized networks instead of putting in the hard work of discovering a decentralized solution. The general public might not know or care what this means to them.
