IMHO:-
There will be a demand for air travel in 2010, 2050 and probably 2100. People aren't going to revert to sea travel. Despite OPEC deliberately cutting supply, there is sufficient oil for the time being. And in 50 years time aircraft will be powered by something else anyway.
As for pilots: unless all aircraft are flown solely by computers, there will be a need for pilots. Perhaps the demand will be for fewer pilots because there are fewer aircraft, and certainly fewer pilots will be needed than are actually qualified, but that demand will be there.
If you don't have the drive to be one of the few to get work, heed the advice, give up now or don't even start.
