For $15,000,000 USD would you allow a robotics company to use your likeness for whatever they wanted?
Some of the uses include billboards, magazines, Android skins, video software. However it would only be for 20 Years they have to stop or renegotiate for future use. They already know based on test analysis your image would be in high demand but the $15 million USD is their final offer. You also get some backend should the company make more than expected and they’ll give you 1% if everything over their projections for the next 20 Years.
Keep in mind you have zero control of how they use your image would you do it even if it could end up everywhere including personal android skins.
Would you do it?
Think of something like David from Prometheus.
Remember you get no control over it’s use once you’re paid it can be used for anything to anybody the company sees fit.
