>1) Creating limited editions of generative art.
I personally think that it's not really an interesting feature. Creating
scarcity out of something that ought not to be scarce is just a way to
infiltrate capitalism in every aspect of our lives. Hacker culture historically
went completely against that (phreaking, breaking DRM etc...) but I concede that
it's more of a philosophical/political argument than a technical one. I still
find it utterly depressing.
I would also argue that there's usually a significant difference between
ownership of a token on the blockchain and what the local IP laws says. IP law
is messy and sometimes subjective, putting things on a blockchain can make
things messier rather than simpler.
>2) "Forever" art like on-chain pixel and ASCII art.
So that one is interesting, but I would argue that it's only true if you
consider that the blockchain is "forever". In order for that to be true it means
that you have to believe that your blockchain of choice will be considered
significant enough by a number of people across... well eternity really. This
could be true for the "big" ones like Bitcoin and Ethereum, although I'd say
the scene is way too young to be sure of that. It's as good a bet as any I
suppose.
But here's the thing. We already have "forever" digital "art": the source code
of the Linux kernel. There are countless copies of it across the globe, and
it'll remain archived for the foreseeable future.
My point here is that if something is significant enough it won't be difficult
to convince a bunch of people across time and space to archive it. People do
that for old videogames, music albums, usenet posts etc... And unlike the
blockchain you can actually curate it, you don't have to archive the neighbor's
sandwich picture collection. I'd argue that this curation power is a feature,
and the fact that the blockchain just stores everything forever is a bug. It
actually means that the bigger the blockchain grows, the less likely it is that
people will want to store personal backups of it.
So I don't think the blockchain does anything novel here, and I don't think it
does it better. Forcing arbitrary people to store arbitrary data forever
regardless of value or interest is just wasteful.
>3) Frankenstein-like adaptations of traditional fintech constructs into a decentralized implementation, such as AMMs.
I think the oracle problem is really going to make "DeFi" a tough sell. There
is, in fact, a lot of trust in our financial system, and being able to use a
central authority (the justice system) to settle issues makes things a whole lot
simpler and efficient.
In general I firmly believe that trust is usually a good thing that makes
systems more efficient and this obstination of cryptopeople to get rid of it is
more based on political ideology than pragmatism. Trust, but verify. But
trust.
