Like with any long-term plan, I had to make reservations. My immediate goal for the flight would be to study Russian and American engineering approaches and to learn from the experience.
Basically, most good science in space flight has to do with the behavior of the human body in space. That is where we are lacking info, and where info can only be obtained by flying in space.
I consider my future flight to be a small part of an important trend to make space accessible to more people, not just to experts. I am very much in favor of commercial space travel, which promises to advance technology just like commercial aviation did many years ago.
