I think the problem is the most important.

Does it solve a real problem? Does it worth me the extra work to solve my problem?

Because at the end, I might be able to solve the problem in another way, that is less convenient, but cheaper, so it does not worth to switch to this new thing maybe.

So kind of the "quality improvements" matter. How much my life gets better compared to its cost? Does that worth it?

And the "worth it" can also be in time as well. 

 And the cost can also be the hard usage 

 👍 agree.
Real innovation will replace existing solution, what we call disruption. Bitcoin is doing that to money/banking and many other aspects of life we may not even recognize yet.
Same might likely be true for nostr.
 

 The hard part is when something is solving a real problem that is invisible to many.
