I feel like I saw a question similar to this in practice exams, and I think 2.0 was the answer, but it could be outdated.

The information about Vitalik Buterin and smart contracts is interesting, but I'm not sure how it relates to the specific question about Ethereum versions. I'll have to focus on that part.

Haha, Ethereum 4.0? What is this, the iPhone? I think Vitalik and the team would like to keep it simple with 2.0 for now.

Needs to stick to the basics first! 1.0 to 2.0 is a big step.

I'm not so sure about that. Ethereum is more like 3.0 to me, with all the advancements in decentralized applications and the move towards Proof of Stake.
