Is golem useful?

As a professional in the field of cryptocurrency and finance, I often encounter various projects and tokens, each with their own unique selling points. One such project that has piqued my interest is Golem. But I must ask, is Golem truly useful? On the surface, Golem aims to be a decentralized supercomputer that leverages the computing power of idle machines around the world. This sounds promising, but does it actually deliver on its promise? What practical applications does Golem have? How does it compare to other similar projects? Moreover, what are the economic incentives for users to contribute their computing power to the Golem network? Are there sufficient rewards to motivate widespread participation? And lastly, is Golem's technology secure and reliable? These are just some of the questions I have regarding Golem's usefulness and potential in the cryptocurrency and finance landscape.
