Yes theres still a long way to go for projects like neuroneum. They got a great model and huge team experience but we cant take away the fact that theres competition and neuroneum would need to learn a lot from existing projects to beat them to the top.
Every new project would have to learn from the older ones. Build/improve on the success of past project. I dont know of any project that plans to build a marketplace for computing power but there are lots of projects on cloud mining.
