Ask HN: Monetizing Idle Computer Power Viable?

There are over 1.8 billion desktop gamers as of 2021, these expensive machines sit idle over 90% of the time on average.

My startup has been aiming to monetize different both the idle computing power (currently through mining, working on providing generative AI APIS), and bandwidth sharing (currently with a partner in the industry but eventually on our own).

Users are incentivized to download our program since they are able to easily earn a small amount of passive income by having the program at letting it run (100k+ downloads so far).

Do you think this idea is viable in the long run? We expect earnings for users to more than triple on average when we move to AI workloads, and companies can save 50-70% off leading platforms by using our APIs. I am worried we will run into challenges finding customers for our APIs.
