That was then; this is now - a look back 50 years ago

Actually, the LED was first developed in 1927 by Oleg Losev.

True, but back then the light was too dim to be of any real use.
The first practical LEDs were developed in 1962

Remember "Vertical Hold" knobs?

And clunky channel selectors with the fine-tune knob around the outside.

And they had valves so you had to have a box of new valves nearby to swap in when they inevitably failed.

And TV licenses . Still a thing in Ireland apparently!

I was a senior in high school in '72.

I was BORN in 1972…….………about to celebrate #50 next month!

More memories of '72:
Working on my car. Adjusting dwell angle and timing.
Setting the gap on the points.
Adjusting the carb mixture and idle speed.
Lubing the suspension and changing motor oil every 3000 miles.
Vinyl seats and landau tops.
Whitewalls.
Bias ply tires.
Recaps.
4 wheel drum brakes.
Heh.

All the things of the past have mostly gone. All of today's things are here temporary, Things of the future seam unreachable.
I like looking back at simpler times and wish they were still that way, to some degree.
Here's something, a little something to work your brains on.
Try and imagine what model rocketry will be like in 50 years?
Will it be common for the average Joe to go in his back yard and take the family on a weekend trip around the World in Orbit?
Will model rocketry even exist? Given the population growth for the past 50 years, and if it continues, will we have room to launch?
Will Low Power be our only option? Or will they be obsolete?
For me, I could care less. I won't be around in 50 years, LOL.
I think I lived in one of the best times in history. Just for watching the Moon Landing alone was worth my time period.

Maybe we will be experimenting with small versions of the gravity drive systems they will be using on regular spacecraft? Probably won't be able to store enough negative mass so our altitudes won't be a high as the commercial rockets.

Also, don't knock hobbyists for R&D. Amateur radio is a great example of this, where amateurs have developed hardware or algorithms that have really improved the art of communications and contribute greatly to knowledge of the subjects.
