Growth Forever

A while back, I’d written about Yuval Noah Harari’s comment from his first book, Sapiens, that capitalism and consumerism are intertwined, that the combo is like the “shark that must swim or suffocate”.

The instinctive reaction of many to that is one of revulsion: why is everyone so greedy? Can’t we just be satisfied with our current comforts and possessions? In his follow-up book, Homo Deus, Harari answers those questions by using India as the example:
-         India’s population is growing at the rate of 1.2% p.a.
-         Simple maths then tells us that unless India’s economy grows by at least the same amount each year, “unemployment will rise, salaries will fall and the average standard of living will decline”.
-         Next comes the kicker: even if India’s population stabilizes, and the middle class is satisfied with its current standard of living, “what should India do about its hundreds of millions of poverty stricken citizens?”
-         If the pie remains the same size, “you can give more to the poor only by taking something from the rich”:
“That will force you to make some very hard choices, and will probably cause a lot of resentment and even violence.”
-         Therefore, the pie needs to keep growing.

All this brings up the next questions, as Harari then points out:
“Can the economy actually keep growing forever? Won’t it eventually run out of resources – and grind to a halt?”
But we’ve heard this many times before. So why haven’t we hit the limit so far?
“Science has provided modernity with the alternative… There are three kinds of resources: raw materials, energy and knowledge. Raw materials and energy are exhaustible – the more the use, the less you have. Knowledge, in contrast, is a growing resource – the more you use, the more you have.”
And so, says Harari:
“The greatest scientific discovery was the discovery of ignorance.”
Given that science has helped discover “fresh sources of energy, new kinds of raw material, better machinery and novel production methods” ever so often, who knows what the next-in-line technologies, “nanotechnology, genetic engineering and artificial intelligence” will produce? And who knows what will come after those?

Those who consider the resources of earth as the upper limit, remember we’re already considering mining asteroids for metals. The argument that we’ll run out of resources is hard to believe when we seem to be expanding the scope from earth to the entire visible universe… the only constraints right now seem to be the limit at which we (or our instruments) can travel (aka speed of light) and the risk of our extinction before we manage to colonize other parts of space.

Student of the Year

Image
As a toddler, my daughter loved Alia Bhatt’s songs, esp. the ones from Student of the Year . (That movie did have many good songs and well-choreographed dances). Fast forward to present day, when she is 12 yo. She rarely watches Hindi movies now, but one of the few ones she likes of late, Raja aur Rani ki Prem Kahani has, yes, Alia Bhatt.   If I had any hopes that there was anything to be read in the name of her toddler-time favorite ( Student of the Year ), they have been dashed. Our conversations come exam time are perfectly captured by this photo and its caption: In fact, the pic below captures how she and I look at her answer sheets – me intently, she with an expression of “It’s over, so why are you even looking at it?”   Of late, we pull her leg and tell her that she isn’t showing any signs of academic prowess, she’d better find a rich guy to marry. Some time later, she showed us this meme on the Internet: “Me No Study, Me No Care Me Go Marry Millionaire If He Die

Animal Senses #7: Touch and Remote Touch

Instinctively, we think touch is based on contact. Not entirely true, explains Ed Yong in Immense World – there’s a more important aspect than contact: “These incredible feats are possible through movement. If you rest a fingertip upon a surface, you can get only a limited idea of its features. But as soon you’re allowed to move, everything changes. Hardness becomes apparent with a press. Textures resolve at a stroke.” As you run your fingers over a surface, they hit the tiny peaks and troughs and set off vibrations in the mechanoreceptors at their tips.   At the tip of its snout, the star-nosed mole has many pairs of hairless appendages. It uses them to touch things around itself. Alive or dead? Food or ignore? It does these movements at an insane speed. In the time it takes to blink our eyes, the star-nosed mole can probe, identify and swallow its food. “Light may be the fastest thing in the universe, but light sensors have their limits, and the star-nosed mole’s sense of

The Retort of the "Luxury Person"

Image
Coming up with biting and witty retorts. It’s something we dream of, but rarely manage to pull off. Worse, the more we stew over the offending remark, the more likely we are to come up with that dream retort, as Calvin ruefully points out: During our last holiday at the Taj Resort, seeing my wife carrying towels to our poolside chairs, one of the kids there mistook her for a member of the staff and asked for a towel. When my wife narrated this to us, I did not imagine that my 8 yo daughter would come up with her own retort. But a day later, my daughter recapped the incident, an incident that didn’t even involve her in the first place , and said, “You know what I’d have told that kid who asked for the towel?”. And without waiting for an answer, she told us anyway: “I don’t work here. I too am a luxury person who is living at this resort. Go get your own towel.” We were highly amused by the phrase she had coined: “luxury person”. It certainly captures the kind of holid
