That's the age old question - what if Facebook copies what you did, in a week? Like they did with Twitter or Snapchat?

By the time they copy you, you're already big. I don't really see the problem as long as the tech companies don't hoard the information and spread the knowledge - which they are doing with initiatives like OpenAI and many more.

The big question is, what happens when they invent AI that builds its own programs and exponentially accelerates? Who needs startups at all then?
