Seems unlikely. Essentially all animals with a brain sleep, even flies. You'd need to find a pill that could do something that not one animal was able to evolve to do over hundreds of millions of years. Something that was extremely calorie intensive is all I can imagine.
I appreciate your logic, but there is a wide variety of needed levels of sleep among different animals, and even among different individual humans which tells me that some are more efficient than others at sleeping (maybe clearing toxins?).
As efficient as evolution is, the ability not to sleep as much may not be a huge determinant in reproduction. Just 100 years ago, people worked all day, then relaxed and slept. There was little to no demand for not sleeping at all from a survival standpoint.
The main reason people want to stay awake all night now is to work more and advance their careers. You don't need that for survival.
Further, Pharma companies have done some amazing things. While I agree that it is unlikely soon, I am confident that if humans are around in 200 years, it becomes much, much more likely.
