I think it's hilarious. when I was in school, microprocessors were 8-bit. Then as the world got digitized it was 16-bit microprocessors. A least in my narrow world. Then 32 bit and floats came along and finally double floats. Each step was a big product effort and launch we sell as better technology. And just as we are finally got past the need to always make both 32 and 64 bit versions of everything, we turn around and head back down. Though I saw someone (Qualcomm?) with a press release about their next gen microprocessor supporting 32 bit floats! Not sure if it counts as another U-turn or they're just a straggler.
