Month: April 2025

“Life breaks free, it expands to new territories and crashes through barriers painfully, maybe even dangerously, but, uh, well, there it is.” – Jurassic Park

“You miss 100% of the shots you don’t take,” is great hockey advice from Gretzky, but don’t go quoting that at an AA meeting.  (“Eh Eh” in metric)

Throughout history, mankind has faced limits.  How we vaulted over those limits has defined our progress, and the bigger the hurdle, the greater the payoff.  Of note, each of these has led to extreme economic and societal disruption.

1. Fire = Mastery of Energy
Barrier Broken: Darkness, Vulnerability, Need to BBQ
Fire was our first “aha” moment, going back to into deep time – our control of this allowed us to, for the first time, harness energy stored in hydrocarbons at will.  Does Grug want warm cave?  Grug make fire, make cave warm, cook aurochs steak, eat.  Good.  Cold hungry Grug sad.

Fire also kept saber-tooths at bay keeping Grug from being a kitty-treat, and turned rock shelters into the original man cave, dreaming of a time when Door-Dash™ would allow people from India to bring bacon cheeseburgers to us.

Simple – if you won’t eat delicious bacon cheeseburgers for a month, no admission to the United States.

2.  Agriculture = Beer + Cities
Barrier Broken: Food Scarcity, Invites to Kegger
I’ve written about this before – Evidence from sites like Göbekli Tepe hints the purpose of the site was religious, but also that it was a brewpub.  It’s likely early brews fueled rituals that glued folks together.  Fire kept us warm, but beer got us buzzed.

The barrier of unpredictable food was shattered when we started planting grain—surpluses meant we could ditch nomad life, build mud-brick condos, and let some dude specialize in carving spoons instead of stabbing mammoths. Result: cities, labor division, and the glorious chaos of civilization, all toasted with a pint.  Or three.

3.  Writing = Records + Reach
Barrier Broken: Fleeting Memory, Knowledge Becomes Eternal
Scribbling on clay kicked off with debts (“You owe me five sheep after you drank all my beer”) or god-shoutouts.  These had taken place orally, but, you know, the last guy I lent a $20 to forgot about it even if I haven’t.  Writing cracked the barrier of oral limits and memory.

With writing, knowledge stuck around—grannies didn’t have to recite everything anymore. Pharaohs sent exact orders to the Nile’s edge; Rome ran an empire on scrolls. It wasn’t just records—it was power, precision, and the ability to tell your great-great-grandkids exactly how to brew that beer. Result: generational wisdom, bureaucracy, and legions marching on paper trails.

But you have to feel bad for her – no one hit the glass ceiling that hard since Goose from Top Gun.

4.  Wheel = Friction Fighter
Barrier Broken: Immobility, Distance Becomes Cheap
The oldest surviving example of a wheel was found in Slovenia, and dates back over 5,000 years, proving that people were trying to get out of Slovenia even back then.

The wheel smashed the barrier of schlepping everything by hand. Suddenly, a cart could haul what ten Grugs couldn’t—trade routes bloomed, villages linked up, and armies rolled instead of trudged. It’s not sexy like fire, beer, and steak, but without it, no ’69 Camaro™.  It’s likely that agriculture made it so we had stuff to move around, and was the real motivator for the wheel, so we could help friends move on the weekend.

Cities got bigger, goods got cheaper, and we stopped throwing out our backs for a sack of grain. Result: the world shrank, and we got mobile.

5.  Printing Press = Knowledge Flood
Barrier Broken: Elite Access, Knowledge Becomes Cheap
The wheel shrunk the world, and then Gutenberg’s clunky printing press took writing’s exclusivity and yeeted it out the window. Books went from monk and king-only treasures to peasant-readable pamphlets—ideas like “Hey, maybe the Earth’s not flat” spread like gossip at a dive bar.

The barrier of gatekept knowledge crumbled—science surged, religions splintered, and revolutions brewed. Result: mass literacy, a brain explosion, and the Renaissance popping off like a medieval Ozfest™.

My HP™ printer joined a band – I should have seen it coming:  it loves to jam.

6.  Industrial Revolution = Muscle Swap
Barrier Broken: Human Power Limits, Horsepower Becomes Cheap
What did we do with all that knowledge and science?  Mastered energy.  Steam hissed, gears turned, and suddenly one machine outmuscled a village. The barrier of physical drudgery got smashed—factories churned out goods, trains hauled dreams, and kids stopped pulling plows (mostly).

Think of this one as taking the first example, fire, and making its use precise and scientific – it’s no coincidence that thermodynamics was the science boom of the 19^th Century, one that made millionaires out of people who could figure out how to make a heat exchanger.  Which is as it should be.

Result: skyscrapers, global trade, and the bittersweet birth of the 9-to-5.

7.  Electricity = Power Everywhere
Barrier Broken: Localized Energy
A byproduct of the Industrial Revolution was the power revolution. Edison, Tesla, and pals flipped the switch, and energy stopped being stuck near coal pits or waterfalls allowing the Industrial Revolution to be everywhere. The barrier of “where the power is” vanished—lights buzzed in hovels, fridges hummed, and telegraphs chirped across oceans.

It supercharged industry, lit up nights, and made “unplugged” a choice, not a fate. Result: a wired world, 24/7 life, and the electric hum of progress.

I told my wife if she was cold and couldn’t find her sweater, she should stand in a corner.  They’re generally pretty close to 90°.

8.  Computer Revolution = Cheap Math
Barrier Broken: Slow Calculation
Now, what do we do with all that juice?  From punch cards to processors, computers turned math from a monk’s headache into a microchip’s yawn. The barrier of tedious number-crunching fell—rockets soared, genomes unraveled, and your phone now out-thinks a 1960s NASA lab.

It’s not just speed; it’s scale—billions of ops a second, cheap as dirt, and my computer has more five times more transistors than the number of people on Earth. Result: digital everything, from Moonshots to memes.

9.  The Internet = How To Be Everywhere, All At Once
Barrier Broken:  Presence at a Distance
Now we had tons of data, but it wasn’t with you.  Until the Internet.  Ever want to go to the library to get a book?  Now I can do it on the Internet without having to ever even haul my PEZ™ powder covered carcass off the couch.  I can pull most movies ever made with a click, I can get facts that would take me days to research in 1990:  immediately.  And I can even order that PEZ® from Amazon™ at 2AM.

Result:  Access to virtually all of human knowledge, and cat pictures.

I belong to a family of failed magicians.  I have three half-sisters.

10.  AI = Cheap Consciousness
Barrier Broken: Mental Bandwidth
Here we are—AI’s making thinking a commodity by meshing 8. And 9. But it is not just crunching data; it’s reasoning, riffing, and dreaming up horoscopes faster than a caffeinated astrologer.

The barrier of human cognition’s limits is cracking—it can synthesize your ideas, spot patterns, and serve it back with a wink, all in real time. Result: a flood of synthetic smarts, amplifying us, challenging us, and freaking us out a little.

We’ll end with these 10.  Note that each of these revolutions had massive and unequal impacts on humanity.   The implications or 8., 9., and 10. are still unfolding, and number 10. is in its infancy.

Since nobody has time for a 2,800 word post, we’ll pick up the gauntlet of what barriers are left, and where we’re headed with AI, and guess at the economic impacts to come . . . but we’ll do it next week.
