Is sharding a realistic goal for Ethereum? How would it be implemented?

I am not an Ethereum developer or expert on the codebase or technical capabilities. In fact I've read very little on how this sharding would be implemented. I have a lot of experience in distributed systems so I understand the benefits but I don't know how this would work for blockchain technologies.

However, it is a known issue and there are proposals and I'm sure more to come. Sharding is a leading proposal and it has been described. However, I cannot personally comment on the viability.

But I'm an optimist and believe it will be solved. Maybe not with Ethereum but eventually with something.

The one fallacy to be aware of is a lot of people it appears think that blockchain technologies are static. As if they can't evolve and change and iterate. They can and if history is any indicator they will so long as there is interest and outlandish people see potential.
