A telephone call in the year 2020 would probably not be just a phone call. It could be a video chat where the screen pops into the sky soon as you answer it. A future phone call could even be a hologram of the person you are talking to. We already have voice dialing in the year 2012, in the year 2020, we might have “mind dialing”. Eating a meal in the year 2050 with my family, I will be sitting down with all my children and grandchildren and their children. Eating space food, dipping dots, or food that comes out of a tooth paste tube. Maybe even like back to the future when they popped a tiny pizza in the micro wave for a minute and it came out a huge pizza hot and ready. When I joined the military and saw an MRE for the first time I thought it was one of the coolest things ever.
By the year 2025 to do a homework assignment I believe we will have touch screen lab tops, watches, I-pads, etc. and everything will electronically be submitted for further review. Going even further into the future and doing a homework assignment in the year 2125, we may have mind writing where u just think of what you want to say or do and a computer automatically does it for you. Overall I don’t plan on doing any homework in the year 2125 so I will probably never know.
