I think this is a limited definition of what an NFT can be.
You are describing counterfeit art and is easy to identify
That's like pointing out how many fake Gucci bags are out there and dismissing the real Gucci by saying "in most cases the creator of the Gucci bag is not Gucci."
Also to avoid scams as an investor, you'd typically want to invest in artists with a reputation.
If the future of the metaverse is on the blockchain, each digital identity will have a reputation to uphold. I think transparency in people's actions, a reputation system, and a simple moderation system is sufficient to manage toxic behavior.
> Its primary feature is to strongly tie someone's identity to their physical body.
I am just being skeptical here. Again, why cant I just have a control panel with a wide range of avatar emotes, the same way we currently have a wide range of emojis.
My physical facial expressions are limited. What if I wanted my jaw to literally drop on the floor? Or my heart to beat out of my chest?
I am not sure if the issue stems from enabling audio. We see this over text on facebook, reddit, and pretty much every gaming platform.
I am a little skeptical of this vision. And I imagine most of the "metaverse" will be experienced through flat screens - and text, voice, and video will remain dominate. VR will grow but do we really need to map our physical expressions onto an avatar to play games or collaborate together? Why go through all this complexity when we can just have controls to enable our 3D avatars to emote?
If you really want to convey facial expressions and a personable experience, just enable video.
You use your private key to verify ownership. In the digital world, this is the closet you can get to having the "original thing". You can disagree with this, but it doesnt matter because obviously the NFT market believes in this.
Some NFTs just sit there, the same way an original piece of art will just hang on a wall. However, some NFTs can have 'utility'. For example, owning one can qualify you to buy a piece that is exclusive to collectors of a particular artist. The artist can also verify holders and send out physical products. Some artists are using profits to re-invest in larger scale NFT projects as well, like virtual worlds and games.
Machine learning is the study of computer algorithms that improve automatically through experience and by the use of data.
This definition would include something as simple as linear regression.
Linear regression attempts to model the relationship between two variables by fitting a linear equation to observed data.
The purpose of a neural network is exactly the same as a line of best fit. That is, you are just approximating an unknown function based on input/output data. The only difference is that a NN can better approximate a nonlinear function.
