Another reason why you won't see practical applications for a while is that we aren't really sure yet whether indistinguishability obfuscation exists at all. The first proposed construction has recently been broken [1], and while other candidates do exist, they are mostly based on similar principles, so most experts wouldn't bet a lot on their long-term security.

This is a rapidly evolving field, though, so I'm cautiously hopeful that some genuinely novel ideas will emerge soon to overcome the current stumbling blocks.
