I will let out a bit of a secret.

I have been running a full IBM System/370 Mainframe on a $5 Raspberry Pi Zero for ~5 years.

About 7 times faster System/370.

Millions of lines of COBOL JCLs running flawless on a battery.

Tested an entire bank’s mainframe COBOL on it.
This is one of the MVS System/370 emulators I have used with great success on Pi: wotho.ethz.ch/tk4-/
APOLOGY.

I want to give clarity: I have great respect for old and new Mainframes, COBOL and other software. I have great respect for the folks that work on these systems today.

My nerd/geek tweet was about my amazement of getting Pi to do this.

The Pi does not replace them.
APOLOGY-2.

The limits of twitter and my style created some ill feelings with some folks on this tweet. I can see how my series of sentences in the tweet could be taken without knowing my prior love of this stuff.

No—an entire bank can not run just on a Pi—but the test worked.

1/ For the last month I have been plotting out the residual effect from the 2020 Pandemic.

I studied past pandemics particularly 1919 and have ideas.

I feel it useful for the incredible minds here to consider:

How will society change and how can your ideas impact this change.
2/ Technologies will shift because of the 2020 Pandemic to a level that is permanent in most lifetimes.

One opportunity is for:

Real-time feedback
Real-time mitigation

From the simple to the most complex.

eg: Mitigation can be as simple as copper/brass human contact points.
3/ The 1919 Pandemic and the Epidemics in Japan/Singapore had a massive impact on behavior and use of new technologies to mitigate.

eg: Japan/Singapore became one of the most hygienic societies—for better or worse.

The US approach was earlier and more documented.

Consider the Photoautograph of Édouard-Léon Scott.

In 1850 he captured the first human voice.

By printing his sound waves on paper using coal dust and a feather.

He called it Voice Calligraphy.

They called him crazy.

“you can’t do that"

They are gone—his voice remains:
Why don’t you know about Édouard-Léon Scott.

Why did it take a century for his Photoautograph ideas to become a reality?

Like always the “debunkers" & “scientists” of the epoch branded him a charlatan.

He died disgraced, alone in an unmarked grave:

“Something must be done about Édouard-Léon Scott”—Scientists & religious leaders, France, 1850.

Mobs formed:

“Mr. Scott driven by overly vivid imagination seeks in these traces information in a higher order, he believes in these inscribed lines, is articulation. He is in error”

Consider: millions of years ago our antecedents gave a massive sacrifice of their left hemisphere.

We lost a tremendous amount of short term memory and replaced it with Broca’s, Wernicke & the phonological loop.

But why?

So we can—talk.

Thus chimpanzees can do this—we can’t:
Every animal has a limited amount of brain power and size, so every skill and talent has an opportunity cost. This is not controversial or particularly questioned.

The Cognitive Tradeoff hypothesis is about tradeoffs apparent between chimpanzees and human.
In 1956 "The Magical Number Seven, Plus or Minus Two: Some Limits on Our Capacity for Processing Information” by George A. Miller of Harvard University was published.

It was a landmark of human memory research.

Bell Labs adopted memory chunking in phone numbers (xxx)-xxx-xxxx
