Creating new ways to interact with the world.

People can collect and trade items of virtually any kind that virtually represent anything digitally. They can also be programmed to perform tasks to do anything on the chain.

Basically it's creating a whole new platform that isn't controlled by anyone and everyone can contribute to it as a user or a contributor (NFT creator, contract designer etc) to suit different use cases.

Just because some actors use it to scam obviously doesn't mean that the whole ecosystem is bad.
