That’s a bit disingenuous. Ethereum isn’t as static as bitcoin; they’ve been making steady progress. Proof of stake also has started rolling out already
The question as I interpreted it is "what has he not yet delivered on" - not "what has he promised to deliver on and appears to be making progress on, and has started rolling out, but is not yet broadly available" :)
Yes, let's rely on word play to make it seem that ethereum isn't being actively upgraded as we speak ;)
Kidding aside, I would think that most people understand "what has he not yet delivered on" as "he's completely broken his promise and he's no longer working on it". I didn't have a "yet" in that sentence.
