My candid advice, before you invest in a project ask yourself;
1. What are the benefits of this project to the world and the future?
2. In the next 2 to 3 years, will the working product still be relevant?
3. Who is the targetted audience? Do the targetted audience really need this innovation?
Agree with all of the above.
So how can you find out all about this information?
Ask them directly and better be good at reviewing their answers.
They can all say the sweet words to you but that should not all be the reason to agree with them.
Better, do not agree yet, and try to dig more into whatever their real purpose is.
Is it for innovation or just a mere profit?
