Some of their predictions, seem to be spot on. There may be other things I missed or forgot, but ...
Online/virtual shopping, seeing the purchasable items on a thin, large screen (and hence the internet, sort of).
My Grandmother used to ring up the corner store, they would pack & deliver----all that went away with self service supermarkets.
Large retailers sent out enormous catalogues with pictures of all their stock, so people could buy remotely.
A computerised version of either of the above was pretty much a "slam dunk" prediction.
Finding out about things a long way, away, such as the weather in a far off place (i.e. Internet again).
Already possible in 1967, by watching TV.
The Chess playing computer is potentially spot on.
Again, already something that had been done in the 1960s.
The large, wall mounted, flat screen (TV/monitors) pretty much spot on. We these days can use flat screen TVs or projectors, to do it.
Not a huge leap in 1967----Ideas for wall mount flatscreens had been worked on by the Electronics industry for years.
They were always "just about 10 years away"!
The rather thin, TV/monitors on desks, pretty much spot on.
Looking a bit too far forward--CRT type monitors were still more common in 1999.
The food being frozen (potentially spot on), then microwaved (spot on, although a few seconds to heat up is a bit on the quick side).
As I've already pointed out,such "TV dinners" were already well known in the 1960s.
People warmed them up in conventional ovens rather than microwave ones.
Not really spot on, as they are still not the normal way food is consumed.
The disposable food serving containers (**Hides Pizza boxes and microwave meal disposable cardboard thingies**, Joke) potentially spot on for some people.
They totally failed to predict the rise of takeaway food, though!
The various plentiful computer systems they suggested, potentially correct.
No big, central computer, though, & the microprocessors in most home appliances do what mechanical switches or bi-metallic switches already did quite adequately!(Fortunately!!) they don't seem to have invented the BOSSY computer, which tells you how much exercise you need, each day.
People wear computers that nag them instead via their smart phones.
I agree with many of your points, but not all of them.
Your Grandmother ringing the local store.
A long, long time ago, we had Green Shield Stamps (UK), which were given out when you purchased Petrol.
You then had a catalogue (very similar to a modern day Argos catalogue), which had a huge range of stuff you could choose to buy with those Green Shield Stamps.
So in a sense the Green Shield stamps catalogue purchasing system, was a bit like the modern day online Amazon ordering (or Argos). But if anyone wants to disagree, I accept they are nowhere near 100% equivalent.
You said "Already possible in 1967, by watching TV." as regards long distant weather reports.
I don't think that is the same, because with the internet (and shown in that 1967 clip), you can do it at
ANYTIME. Whereas TV weather reports, are only at certain times (at least in countries without thousands of TV channels).
"The Chess playing computer is potentially spot on."
"Again, already something that had been done in the 1960s."
But the thing is that in the 1960s, playing Chess against a computer could only be done inside a very small number of computer centres (e.g. University). It could not in general be played at home, unless you had a big (in the 1960s) computer at home, or a terminal to one. Which was extremely rare (at home) and unlikely in the 1960s.
"The rather thin, TV/monitors on desks, pretty much spot on."
"Looking a bit too far forward--CRT type monitors were still more common in 1999."
I agree with you. I was somewhat too early, for 1999.
From memory, I think it was 2001 and definitely 2002 when they became increasingly common place.
So not exactly miles out.
"(Fortunately!!) they don't seem to have invented the BOSSY computer, which tells you how much exercise you need, each day."
"People wear computers that nag them instead via their smart phones."
You're right. I'd forgotten about that, and not thought about it like that.
BUT since you have told me off, for claiming LCD flat screen TV monitors were
NOT 1999, but 2001/2 and later. I will have to (Pedantically) point out that it is now 2017, and those nagging exercise apps/gadgets were not around in 1999, as far as I can remember.
