Not really?.. :)

I think this argument is typically brought forward by newer entrants to Bitcoin (although not exclusively), and it might be because they’re simply impressed by bitcoin elegance and usefulness, and the impact it can have on their lives. As such they believe it already does all it would ever need to do. They’re also reinforced by tales about bitcoin’s codebase’s immutability, but of course those tales aren’t true, and bitcoin is upgrading all the time (just maybe not in the ways that would be most impactful).

There’s also another argument which is that upgrading bitcoin is risky and therefore shouldn’t be done. While I can understand that approach, it is not the same as saying that bitcoin doesn’t need new features… it might need them, but this cohort believes that even though they might be needed, we are too stupid to do them safely.
