You can read about some of his publications about Ethereum and “public blockchains” at https://wdai.us/posts/. I think he treats topics that will be relevant for the Bitcoin protocol as well. Nevertheless, they are presented at Eth’s conferences and shared by the Ethereum foundation’s YT channel.

In general, he seems pretty close to and willing to work on Turing-complete chains, something that Satoshi deliberately chose to avoid.

I don’t see anything wrong with it, I just hope Satoshi is still among us coding on Bitcoin and didn’t change his mind on such an important piece of Bitcoin’s architecture. Ultimately, it doesn’t matter.
