The goal - not only money. Sometimes technological advantages more important. It can help country to be more independent and make protection from other countries.
I think world is big. I mean: universe, technologies, quantum effect, love. There are many interesting things besides AI.
What I really trust - only technologies can help us to improve our life and make unlimited experience.
I am not a deep in marketing, but I am just test idea with my friends, then make project page, buy a bit of advertise and read analytics.
It's not necessary big money to prove idea.
