Most of these advances (besides flying cars, they're just dumb) are social advances, not neccessarily purely technical ones. Our cities could be much more futuristic, but that's clearly not due to a lack of technology - it's due to a lack of clear political will. Technology regarding health could be better, but start at implementing a decent health care system that doesn't let people avoidably die because they can't avoid treatment (this is US-specific, but a bad situation made even worse by the president Thiel so vehemently supported). Space travel, again, is in a large part just a matter of funding (we could be at today's point 20 or 30 years ago).
