South Korea is exploring and investing in carrier options as well. More seriously than Turkey, I'd say.
Also, talking about just ambition, Brazil definitely has ambition to operate carriers. Their lack of money forced them to get rid of their carrier, and nothing else. So by 2050 it's perfectly possible they will be once again operating a carrier. Indonesia too might join that club by 2050. If indeed it manages to be so successful economically as the table projects. After all, its an island nation, covering a huge territory - it could be better served by a carrier than some of the other countries on the list.
