What a silly thing to bicker about.
Of course every one of us having a computer many times more powerful than anything that existed at the time yet small enough to fit in our pocket with plenty of room to spare and using wireless earphones (that also boost external sounds if needed) to communicate with it by simply saying in whatever language we speak what we want the computer to do or research and having the resulting confirmation or information read back to us, again in whatever language we'd prefer, as part of our professional remote-work career, as we sit in the back of a driverless car heading home from a nice lunch, where we'll see that the groceries that were automatically ordered and delivered based on the contents of our refrigerators and cabinets compared to the eating preferences and any special requests made by each member of our household are waiting for us... was science fiction in the 70s.
We can add in having whatever music we prefer automatically follow us from our home to our earphones to the car speakers, watching any movie/show or playing any video game from anywhere in the world, using your far more powerful computer at home to do the more demanding tasks but wirelessly using your phone as a monitor to stream whatever game it's playing to wherever you are and having a wireless controller paired with your phone control the character in the game being played hundreds of miles away nearly seamlessly, being able to hold a face to face conversation with someone who speaks nearly any language you that don't via live translation, to share any sort of book or movie or what would amount to a more information than is contained in a typical library to anyone else on the planet in a few seconds to a few minutes without either of you ever needing to stand up from wherever you're sitting... I can go on for a few pages easily.
Yes, those things and way more that we take for granted daily now were nothing more than science fiction in the 70s.
