I suppose these guys didn’t buy a computer, my:
My first computer was a Commodore 64 bought about 6 months after they were first released.
Mobile phones to me are a complete waste of money unless used as a tool at work unlike the tools you see on the train or crossing roads with their heads down.
Flat screen TV, you are correct there. When they were first on the market you were looking at $14000 and up, have you bought a $14,000 TV lately?
I mean, the cost of those were sky high when released. How will the working poor ever afford it? No. Better to stick with Bakelite telephones,
Again, arguing out of ignorance, when we moved into our first home there was a 14 month waiting list in our area to be connected to a landline, the wonders of government run businesses. By the way Bakelite was used because the modern COAL derived plastic that you use extensively had not been invented.
Cathode tubes.
I assume you are talking TV, my father purchased a Pope Motorola 21" B&W TV around the late 50’s for 320 pounds when his wage as a bricklayer was 20 pounds week, 16 weeks wages, work that out in todays values.
Horses
Used to pull the bread cart, the ice cart and up until the early 70’s the milk cart.
Kerosene lamps.
Yes we had kerosene lamps, used them we went camping and also, and this may be relevant, as emergency lighting when the power went out as it did on a regular basis, a condition we are fast approaching in this state. These days you could use batteries but they go flat, Gas, good, but can be in trouble if you damage the mantle, Kerosene, good and reliable.
You forgot to mention driverless cars, I lived in Barkly St in 1955, an old Chinese market gardener would pick his vegetables in Moorabin early in the morning get on his cart and go to sleep, the horse would take to Queen Vic, he would unload get back on the cart go to sleep and the horses would take him home. GPS and driverless car all rolled into one.
