I know that most don't but these are old ideas from around it's founding and there's people I know teaching this sort of stuff. My point is that the idea of dispensationalism was made originally to promote Jews and some of these old ideas that are still around are way too similar to the NWO agenda being said to be a good thing to be coincidence. Personally I think that the people that are clearly true believers will probably move away from dispensationalism or at least the idea that the rapture is definitely this generation when it becomes clear that the rapture isn't coming but there's also a lot of regular church goers and prophecy fans that just like hearing what makes them feel good and that's where the apostates will come from.
