They are useful for categorical variables. For example, is a record in the "Likes motorcycles" category? They are fast because (well, one reason) bitwise logical operations are very fast for CPUs to do.

Adtech is an example of a sector that benefits from this...they slice and dice datasets a lot to target ad campaigns and such. Being able to do that quickly is useful.

Hey! Would you be interested in collaborating on this? I have a wide selection of hardware I'd be happy to contribute as well. You can reach me at my username at gmail dot com.

Sorry about that, I'm still in the process of converting my notes and memories into coherent posts. I just put up another one, and should have the next few shortly.
