I'd say the real breakthroughs there the transistor, and after that
the

Sure, but other stuff like VisiCalc was too. So was Linux.

Linux was and still is just a copy of something that already existed,

No it was not.

its hardly a breakthrough to copy something.

Linux isn't a copy of anything.


It is a reverse engineered Unix, deliberately rewritten to avoid copyright
issues.

So it isn't a copy.

Unix was the real invention, not Linux.

I never said it was the real invention, just that open
source was a significant advance on what was there before.

And that wasn't done in a shed either.

Never said it was.

But even Unix was no more than a logical progression from one operating
system to a better one.

Still a significant improvement on what preceded it.

All the key breakthroughs

We weren't discussing key breakthroughs.

of the 20th century came about from a new understanding of quantum
physics - atomic power and weapons, the transistor, the laser.

That is just plain wrong with DNA alone.

These were true breakthroughs.

We weren't discussing true breakthroughs
most obviously with viable flying machines.

Everything else is simply taking advantage of the things they offered - in
the case of the transistor enormous computing power in a small package -
to do things that people had been doing by hand for years.

Just as true of the wheel, aircraft, cars, the internal
combustion engine, steam engines, etc etc etc.

Open source is more of a breakthrough

And that is what Linux is.


No. that's a small part of what it is,

It is what sets it apart from the other OSs available.

Its WHY it is tho.

and some of the software produced because of it could be a breakthrough,
Linux isn't.

Wrong.

Wright.

It is on open source alone.
