Depends on your definition of smart. If you define smart as having knowledge, then technically, in a way, osu does make you smarter, as you will gain knowledge, but only on osu. If you consider having good reaction time / memory as being smart, then sure you would become smarter.

I was wondeing since while playing osu! that you have to react quickly to get from place to place as well as memorize as you replay the same beatmaps
osu! is not about memorization and I haven't memorize a single map in my osu! career.
Generally, osu doesn't require a good memory, and will do very little in terms of improving it, but just because you haven't memorized a map, doesn't mean others haven't. FL players rely on memory 90% of the time, so if you play FL, then your memory will probably improve, and if not overall, then at least of where and when circles / sliders are in a game. Over the months that my beatmap collection has grown, I also remember and can associate a sound / map with a lot of songs, so it improves it in that manner as well.
