You do not need a crystal ball.
1,000 years from now, we will still be at the Basic Research level.
Profits - if any - will take millennia of Basic Development.
Space tourism and Space Thrill Rides might be profitable - until the first mass casualty event, at which point the lawyers will take charge from the scientists, the engineers, and the entrepreneurs.
I guess you do not keep up with basic physics and propulsion methods. Which are currently outstripping the chemical rockets by a lot; to implement them just require political will and money, not time.
Then there was Project Orion in the 60s, killed in 64 by infighting and lack of political will, but would have had us in the entire solar system by now with the first returns from interstellar flights already happening.
