There are a lot of depin projects, really good ones with goals and solutions. There's interesting one I've been holding its airdrop. Grass Io, which focuses on monetizing unused internet bandwidth and using those data to improve AI..
The demand for AI compute will certainly be a very big usecase for DePin in the cryptospace. This demand will be increased more this year because we have a new entry for the AI storyline. This will be the metaverse with AI inside of them. This will be something similar to the television show in HBO with the title West World. This is where humans' relationship with AI will begin to change.
However, I reckon the hardware power might not be enough to make this world a possibility without DePin hehehe. DePin, AI and the metaverse will be working together to create new products for human entertainment.
