Group bike rides build community

I have been getting a lot of satisfaction lately from group bike rides. Community emerges naturally when people ride bikes in groups. The contrast underscores how automobile culture is a death cult: every driver gets their own sarcophagus for the living to move them through places while keeping the driver sealed apart. The driver is isolated from nature, from community, and from life at a human scale. They begin to live at a car scale where our instincts and experiences no longer bind us to our neighbours. The car is built to move at 60, 80, 100 km per hour, and to be indifferent to anything it might need to kill to do so.

Group bike rides provide a tangible vision for an idealized future without private cars. That’s a world where people who take the same routes and live in the same neighbourhoods know each other and talk: where they are neighbours. That’s a world with flower fairy girls on lavishly decorated cruiser bikes, and with guys in motorcycle helmets and body armour riding on zippy electric unicycles.

On a bike in the city, you live with the constant awareness of being killed. When riding alone, the great majority of my attention is always directed to nearby drivers and what abrupt, dangerous, or illegal thing they may do next. For drivers in the city, they may live with a mild awareness that their every careless action threatens to kill others, but they are distracted by bluetooth calls and streaming media, alienated from their fellow residents by socially atomized affluence, and shielded by public opinion and a legal system where killing someone with your car through simple carelessness is a minor and unimportant oversight which ought not to impede your happy motoring.

Game theory and the limits of reason

I myself suffer from a morbid sense of despair, and even now, decades after I worked with von Neumann, I still find myself questioning our central tenet: Is there really a rational course of action in every situation? Johnny proved it mathematically beyond a doubt, but only for two players with diametrically opposing goals. So there may be a vital flaw in our reasoning that any keen observer will immediately become aware of; namely, that the minimax theorem that underlies our entire framework presupposes perfectly rational and logical agents, agents who are interested only in winning, agents who pose a perfect understanding of the rules and a total recall of all their past moves, agents who also have a flawless awareness of the possible ramifications of their own actions, and of their opponents’ actions, at every single step of the game. The only person I ever met who was exactly like that was Johnny von Neumann. Normal people are not like that at all. Yes, they lie, they cheat, deceive, connive, and conspire, but they also cooperate, they can sacrifice themselves for others, or simply make decisions on a whim. Men and women follow their guts. They heed hunches and make careless mistakes. Life is so much more than a game. Its full wealth and complexity cannot be captured by equations, no matter how beautiful or perfectly balanced. And human beings are not the perfect poker players that we envisioned. They can be highly irrational, driven and swayed by their emotions, subject to all kinds of contradictions. And while this sparks off all the ungovernable chaos that we see all around us, it is also a mercy, a strange angel that protects us from the mad dreams of reason.

Reading Kahneman’s Thinking Fast and Slow recently, at several points I was struck by what seemed like the unjustified assumption that people are competent at mental arithmetic. Specifically, that you can give a person a list of probabilities and payouts and then find it legitimately surprising that they can’t or don’t pick the best one. For people constantly immersed in calculation this may be puzzling, but I also have personal experience of highly intelligent and knowledgeable people struggling at (or being unwilling to even try) calculating what a certain percentage of a number is, like for a tip. Studies on the numerical literacy of the general public reveal a worrisome inability to properly gauge millions against billions.

When mathematicians, logicians, and game theorists forget that much of the population cannot or will not calculate, they miss the obvious cause of deviations from their predictions and theories.

Lonely, frustrated, angry, and despairing

Lately, I have been feeling dejected and wildly alienated from the rest of humanity. It seems like basically nobody wants to avoid catastrophic climate change. Among those who purport to care, the superficiality the commitment is quickly revealed when they prioritize other objectives ahead of avoiding climate disaster. Government agencies work to defend the status quo: at best, they pretend to take action in order to avoid doing anything that would really make a difference. At worst, governments are the armed wing of the fossil fuel industry itself. Every country with fossil fuel reserves is rushing to develop more production. Even climate change activists care more, in practice, for imposing their social and economic preferences on society than about abolishing fossil fuels.

At times over the last 18 years, working on climate change has felt like a lonely journey but at least one where eventually the world will come around. As each year goes by now, it seems more that humanity is content to fly our plane straight into the ground, while the passengers cheer as they set ever-higher speed records and the captain assures everyone over the intercom that our present course ensures a happy arrival at a welcoming destination.

Everyone is still developing fossil fuels

As my recent blackboard talk emphasized, climate stability means fossil fuel abolition. Arguments to the contrary are cynical mechanisms to keep the petro profits coming, regardless of the consequences for the climate.

Unfortunately, despite endless talk about ‘net zero’ and ‘ensuring’ climate stability, essentially everybody is still chasing fossil fuels:

Remember: it takes decades for the full effects of our greenhouse gas pollution to be fully manifest. That means much worse is still to come, even if we start making the right choices, and a nightmare looms if we persist with our current approaches.
