The Rodney Brooks Rules for Predicting a Technology's Commercial Success
"Building electric cars and reusable rockets is fairly easy. Building a nuclear fusion reactor, flying cars, self-driving cars, or a Hyperloop system is very hard. What makes the difference?
The answer, in a word, is experience. The difference between the possible and the practical can only be discovered by trying things out. Therefore, even though the physics suggests that a thing will work, if it has not even been demonstrated in the lab you can consider that thing to be a long way off. If it has been demonstrated in prototypes only, then it is still distant. If versions have been deployed at scale, and most of the necessary refinements are of an evolutionary character, then perhaps it may become available fairly soon.
Electric cars are a relatively easy technology. We have more than 100 years of experience engineering and manufacturing windshield wipers, brakes, wheels, tires, steering systems, chassis, and much more.
We have more than 20 years of experience making digitized drivetrains.
On top of that, we already have a whole infrastructure for driving, including roads, parking spaces, safety standards, auto insurance, and government licensing of both the vehicles and the drivers. So to go from internal-combustion-engine cars to electric cars, you don't have to invent everything from scratch and then figure out how to deploy it at scale.
The self-driving car is arguably the single most anticipated technology right now. Here the difficulty lies in attempting something that has no real precedent.
Last year I wrote in this magazine on one aspect of the problem: the unexpected consequences that self-driving cars might have on human behavior. I pointed out that pedestrians and the drivers of other cars might find autonomous cars a tempting target for antisocial behavior. I also noted that the owners of self-driving cars may use them in ways that they would never use a regular car, perhaps succumbing to antisocial behavior themselves.
Another problem is what are called edge cases, which involve robotic cars bumping up against the limits of their capabilities. Some of those limits are not known ahead of time.
Driverless cars will not simply replace cars that have human drivers. Instead, we'll install special lanes, even geofencing the self-driving cars into lanes or entire roads, of their own, to protect them from human-driven cars and vice versa. Also, we'll change the norms for where it's acceptable to pick up and drop off people, where to park, and many other things.
We'll need changes in safety regulations and in how we assign legal liability. And for the laws to change, attitudes must change.
At first the cars will operate in restricted geographies and markets, such as malls, industrial campuses, and other places where human-driven cars are not allowed. Perhaps they will be restricted to certain times of day and certain weather conditions. The various problems of the self-driving car will be solved—eventually. But it will all unfold more slowly than the enthusiasts think."
I agree with him about the HyperLoop. Nice idea in a science fiction story but in reality sending people down small tunnels at great speed in an earthquake zone does not seem smart to me.
Most technologies start very slow and then once market penetration commences they speed up dramatically, digital watches, desktop computers, mobile phones etc.
As far as LENR is concerned, once the process is mastered and proven safe we do not need any AI, we just need it to plug into the grid, or where the home boiler sits, and generate heat or power.
So according to Rodney Brooks rules I would guess LENR is more like an electric car than a self-driving car.
In the UK at the moment people are being encouraged to swap out their gas boiler and replace it with a heat pump.
Maybe in ten years we will be able to swap out the heat pump and replace it with a Brillouin boiler.
