"which I guess NTL would call low tech simply because they are "old" technology. "
I don't think I implied any such thing. I consider low tech to be uncomplicated simple things most morons with a 1st grade eduction (maybe less) could still build themselfs, and also alot of other things even more advanced than that but still simple and basic.
There is nothing high tech about tying a couple cans together and pulling a string tight for a tin can "phone". You don't have to understand why it works and very small chance of failure when building it yourself at home, no fancy tools or machinary needed, no oil is used to make it. Don't have any string, use an animal tendon, don't have a can, use a chunk of wood carved out in center or a paper cone. Anything that will reflect and amplify vibration, but you don't even need to know that, just use a few things till it works. Try building a cell phone that way
The TV is still high tech, even if it is an old 1950 vacume tube set Black and White and mono sound.
A modern TV, solid state, surround sound, color, remote control, etc... is maybe more high tech.
Drawing stick figures on the corners of a book of paper and fliping the pages fast is low tech.
All 3 show a moving picture.
Burning a stick till chared or using berry juice as ink, and drawing a picture on a rock is low tech. A digital camera, computer, and photo printer would be hightech.
Writing a letter on a rock with a stick and berry juice is low tech, typing and printing it with your computer is high tech, both work just as well to leave yourself a note to remember to buy bread today.
Actaully in this case low tech is better! To type and print the note you need to turn on the PC and wait for it to load software, open a program, type the note "Buy Bread Today", wait for it to print, wait for computer to shut down. Far easier and faster to just open a bottle of stored berry juice dip a stick, write note on rock, close bottle, and no electric was needed to do it so you can still leave the note to yourself durring a power failure
How high tech is it to smash a berry and break a stick? Of course why bother when we have pencils pens and paper.
Of course I would consider some paper and sticks and a piece of string to be low tech to build a kite also, a helicoptor flying at the same height might be a bit more high tech. Both use areodynamics to fly, but to build the kite you don't even need to know that. Both could hold a high tech video camera and take video from the sky.
Use a wireless transmitter camera the size of your thumb on the kite, might be good for about 300' for the signal, video probably crap though, I saw it recently at a chain store for $74. Don't know if it's any good at all, but still hightech. I have actually thought about doing this later, either video from a kite or video from a radio controled airplane.
