From cave painting to cellphone cameras.

When people got their start, they made drawings on the walls of caves.

Then they found they could take the rocks out of caves and carve text and drawings into stone.

Tben they came up writing on parchment (animal skins), papyrus, and paper.

Later, maybe the 1400s, they learned to print pictures and text with a printing press.

Around 1840 Daguerre invented the Daguerreotype.

Later, they learned to use celluloid instead of glass plates.

Then around 1938 someone invented the photocopier.

Around 1948, Edwin Land invented the Land Camera, that produced self-developing pictures, that didn't need a trip to the drugstore.

By the late 1970's photocopiers were plentiful and by the 1990's people had their own at home.

By 1999 the cellphone camera was invented and by now just about every cellphone has one, and 80% of people over 10 years old have a cellphone. One can take picture and print it 5 seconds later straight from the phone to the printer, in many cases.

Yet some people still think a vaccine has to take 8 years to create. They are people who have no idea how to make a vaccine and couldn't make one if they tried for their whole lives.

The problem is adequately testing it and that takes time. You can't predict long term effects from a short term test. You can only extrapolate and guess. They do guess wrong sometime.

Besides, as Trader likes to point out, mRNA research has been going on a long time and this was just an adaption of another vaccine they were working on.

There was a series by James Burke called Connections. Burke would explain how odd discoveries would combine to make a modern sports car, for example.

That was a good series. Mike Rowe has a series on Discovery+ called Six Degrees. Same idea.

Thanks. I brought it up and will play it soon.

Earliest found are from 35,000 to 50,000 years ago. Most likely there are undiscovered cave drawings much, much older. 'People got their start' longer than 50,000 years ago.

Here ends your list of one track of permanent visual communications. (Smoke signals aren't permanent.)

About 50,000 years from beginning to end of your list. I don't see how your statement below flows from all of the above.
