There was a time they thought bicycles were a far-fetched idea. Now they're something that gets stolen and you shrug and buy another one. And when you look at the penny farthing, you realize they took a half-baked idea and turned it into the many types of bicycles we have today that are far better for their intended purposes: BMX, tricycle, 3 speed commuters, 10-speed, 12 speed, 21 speed, etc... and their many variations. I don't think personal rockets will be a thing, but the common cultural thought of it will result in something related, but improved by the injection of actual science, and a cost/benefit response. Electric autopilot is the current closest contender for a "personal rocket" type transportation solution. I'm sure there are others, too. I'm looking at the problem being solved, versus a single potential solution for it.
