When I come across new hyped up tech, I tried to build something with it -- that usually tells me if it's a bunch of hype or something more. With most crypto projects, I find that is _very_ difficult to actually build anything. On many, I have to click through several layers of 'Get Started', 'Learn More', etc. buttons to even get to any technical info.
I was interested in Livepeer, a kind of "Uber for video transcoding". But after hours of trying, discovered the requirements for being a transcoding node were too high for the ordinary user. And using it for transcoding was difficult. AWS Transcoder or running FFmpeg on EC2 are so much more practical. Polkadot and Internet Computer seem neat in concept, but again, too difficult / impractical to do anything either. I haven't tried Solana yet.
Storj, a kind of "Uber for storage" is one that I think it _actually_ useful. Has an AWS S3 compatible API, 80% cheaper than S3, good docs, easy to get node up and running -- it actually makes sense.
