I agree that the core features like fixed supply, pow, high decentralization (aka small rather than large blocks) would stay. Yet lower level features that would enable scaling on other layers are missing (zk, ctv, trustless sidechains, …)

The Case for a Chain Split

He certainly would have made a few changes (i.e. to avoid bugs like the 2011 inflation bug) and he may or may not have made other changes (e.g. smaller blocks).

But his goal of ending monetary inflation would have remained the same. Considering inflation has gotten significantly worse since 2009, Satoshi probably would have been even more adamant that Bitcoin was made to end inflation.

Fortunately, there are plenty of Bitcoiners who have been adamant about that specific goal.
