      For real. Who would have guessed the most realistic prediction from Star Trek was talking directly to the computer. Whereas the least realistic one is that a post-scarcity society would benefit average people.

    Directly measuring gravity waves, the first measurement using LIGO was back in 2016 and they’ve observed almost a hundred so far. The observations are being used to create newer generations of gravity wave detectors.

      That one does blow me away - I’ve had a cordless drill for years, but a tablesaw??? - when I realized they even existed I couldn’t believe it.

        I mean, when you think about it, it’s just a battery-powered circular saw flipped upside-down. Not too crazy to consider like that.

          Battery powered circular saws were also science fiction the day I was born.

          Go watch early seasons of The New Yankee Workshop and look for the cordless power drill he uses in the first couple of seasons. It’s got this gigantic permanently attached battery hanging out of the hand grip (the hand grip is like a foot long) and it can just barely turn a wood screw.

          By the time I was in high school tiny, underpowered circ saws were available that ran on drill batteries. These things had like 5 inch ultrathin blades. Now look at it.

        The first battery powered drills were pretty horrible. Batteries have come a long way

    I don’t know if people were really talking much about this kinda stuff back then, but a PC like device that wasn’t a laptop that allowed you to play full-on PC titles at home, either hooked to a TV or on its own, or on the move. Especially a device that also allows you to do normal computer things outside of playing games.

    Again, not including laptop since I personally don’t know any people who actually used their laptops for playing games while in a moving vehicle. There probably are plenty of people who did it or do it, but I don’t know any.

      Which is only possible because of this magic technology to let you see and talk in near real time to anyone, anywhere. Used to be that if your sibling / parent / other family member wasn’t in town, you couldn’t see them in real time at any time, usually just a single / couple times a year at holidays.

      Sure calling was a thing, but it’s just different when you can see someone.

        Working from my bedroom in the US while seeing and speaking to a fellow developer living in Pakistan is really quite awesome.

    In my pocket I carry a library of Alexandria, an infinite Walk-man, a camera and a camcorder with effectively infinite film, a personal navigator… You get the idea, the list goes on. 80s me would have thought this was impossible, even if I am a bit disappointed about the flying car and hoverboard situation.

      That one cuts deep. It’s really weird too because if you asked your parents they would say america would never elect a felon. Then they went on to elect a felon.

      I sometimes think about trying to reach out to older folks to better understand their views but then I remember the absolute garbage brain rot they believe.

    Satellite navigation. In my early childhood we sometimes played a street racing video game that had an arrow pointing the direction on the screen. My mom would remark that she wished she had such an arrow when she drove a car IRL, by now she definitely got that wish.

      Wait, how old is consumer satnav? I am pretty sure it was available (albeit not too commonplace) when I was a kid in the late 90’s or early 2000’s. I really do take it for granted… As long as my government doesn’t deliberately scramble it for security reasons, which happened a lot in the past year.

        Dedicated units were available from brands like TomTom in the early 2000’s, and cell phones started getting it around 2007 or so (I remember very expensive blackberry plans had it around then). Android launched with it in 2008, and iPhones started allowing apps like Google Maps with turn by turn navigation by around the end of 2012 or so.

        I don’t remember my first gps, but maybe early 2000’s. It was a Garmin, with no route planning, no maps and the position was coordinates
