We might not have flying cars (not in the way you see in sci-fi movies anyway), but we have a lot of other interesting things. Picture this: you travel back in time, the year is 1985. You see someone holding a brand new Nikon FG20. You tell them, guess what, no later than 30 years from now, we'll be having cameras that can give you perfectly usable ISO 6400, 11-point AF with 3D tracking, 5 fps continuous shooting, and you don't even have to load/expose/print film, for less than $500, complete with a decent lens.
Oh, and it records video, too!
They'd probably faint.
Perhaps this might happen to us too if someone from the year 2045 (if humanity hasn't self-destructed by then) came and showed us the Nikons from that year. I won't even bother trying to speculate any possible specs, feel free to share your opinions in the comments below if you have a smart idea!
But guess what? In the end, photography is still the same. Art evolves too of course (we have different aesthetic dynamics compared to 100 years ago), but the basics are still the same. Ansel Adams's photos will continue to look great 100 years from now. So, don't fret too much about technology, and focus on photography.
Better still, focus on the things that truly matter in life, like the people around you and yourself.
Happy Holidays from AmateurNikon!
