Book: Quantum Supremacy: How the Quantum Computer Revolution Will Change Everything Author: Michio Kaku ISBN: 978-0385548366

Chapter 12 is where Kaku connects two big threads from the rest of the book: artificial intelligence and quantum computing. The most interesting part is not the AI history lesson though. It is how both technologies come together to tackle protein folding and brain diseases that we still cannot cure.

AI: From Hype to AI Winter and Back

Kaku starts with the 1956 Dartmouth Conference, where scientists predicted they could crack artificial intelligence in one summer. Many summers later, we are still working on it.

Chapter 11 is where Kaku moves from quantum physics into biology. He covers cancer detection, immunotherapy, CRISPR gene editing, and a fascinating paradox about why elephants almost never get cancer. The quantum computing angle is still there, but this chapter is really about biology and what we now understand about cancer at the genetic level.

Twelve posts later, here is what stayed with me.

Switzerland was not always peaceful

Biggest surprise of the whole book. When people think of Switzerland, they think calm, stability, neutrality. The actual history is full of wars, religious conflicts, civil wars, and political crises. The Old Confederacy nearly collapsed multiple times. Catholics fought Protestants. Urban cantons clashed with rural ones. Napoleon invaded and reshuffled everything. The Sonderbund War of 1847 was a real civil war.

After 1989, the Berlin Wall fell. Cold War ended. Switzerland suddenly had a problem. For decades, the country sat comfortably between East and West. Neutral. Special. The Sonderfall. Now there was nobody to be neutral between. The whole foundation of “we are different and that is fine” started cracking.

Chapter 9 of the book. Honestly, it reads like a political thriller.

The army nobody needed

First shock: in late 1989, over a third of Swiss voters said yes to abolishing the army. They lost the vote, but still. One third. For a country that built its identity around militia defense, that stung. Even worse, after Germany reunified, Switzerland realized its army of 650,000 was nominally the biggest in Europe. A pacific neutral country with the largest army on the continent. Kind of awkward.

Chapter 10 opens with a simple question: how long can you live? For most of human history, the answer was “not very long.” Average life expectancy hovered between twenty and thirty years. People died from things we now treat with a cheap pill from the pharmacy.

Kaku walks through the major medical milestones that got us to where we are today. Better sanitation in the 1800s added fifteen to twenty years. European wars pushed doctors to actually publish results that worked instead of protecting their useless potions. Then came antibiotics and vaccines, adding another ten to fifteen years. So now many countries sit around seventy years life expectancy.
