Ask HN: What does the next 10-20 years look like in tech/engineering?
Specific questions I'm thinking of:<p>- Is it all facebook and google from here on in?
- Are we going to solve the energy crisis?, How about the climate crisis?
- Flying cars? seriously?
- How will quantum computers change things?

- And anything else you want to discuss ...<p>I'm not necessarily looking for hard facts.  Vague opinions can also be interesting.
