From: environment — world economic forum
Repairing goods, rather than disposing of them, might not only have environmental and economic benefits, but social ones too.
This post is structured as a question-&-answer. That’s because it was originally an answer at Quora, a Q&A site at which I am a Bitcoin columnist.
What is a ‘Paper Wallet’
A paper wallet is the ultimate offline wallet. It simply means that the private address to your crypto wallet is printed on paper — either as a string of characters, a QR code, or a series of seed recovery words.
If you destroy any electronic copy of your original wallet (e.g. the private keys that give you access to your wealth), then hiding this piece of paper is very similar to hiding a bar of gold. The only way that someone can steal it or know the amount it represents is to get their eyes and hands on something physical. They would need to know that you tucked it into your mattress or behind a secret panel of your cellar wall.

But a less-noticed win for DeepMind, the artificial-intelligence arm of Google’s parent Alphabet Inc., at a biennial biology conference could upend how drugmakers find and develop new medicines. It could also dial up pressure on the world’s largest pharmaceutical companies to prepare for a technological arms race. Already, a new breed of upstarts are jumping into the fray.
Alphabet’s DeepMind cracked a problem that long vexed biologists, heating up a technological arms race in health care.
Any major breakthrough in extending human life would drastically alter population projections. The social effects, while obviously huge, would depend on whether the years of senility were prolonged, too; whether women’s age at menopause would increase; and how families would be structured if many generations were alive at the same time. Expensive treatments to extend human lives could also have implications for inequality; as in many other areas of technology, the wealthy would be most able to afford such services.
Almost everyone would welcome an extension of their healthy lifespan, and some scientists are looking at increasingly extreme ways to achieve that. But any major breakthrough in this area could have unwanted and far-reaching demographic, social, and economic implications.
CAMBRIDGE – Humans have long sought the elixir of youth, so it is not surprising that even non-scientists closely follow the latest research into aging. But is what most people consider simply a fact of life actually a “disease” that can be cured? Or is there some insurmountable limit to the lifespan of human bodies?
This afternoon, an automated bot at Quora suggested that I answer a reader question. Quora is essentially an “Ask the expert” web site. It is the world’s largest, cataloged and indexed Q&A repository.
This is the question I was asked to answer:
Some pundits believe Bitcoin is a fad, while others seem to feel that it is better than sliced bread. I like sliced bread.* Is Bitcoin really that cool? —Or is it just a lot of Geeky hype?
One other columnist answered before me. Normally, I pass on an invitation, if a question has already been answered. But in this case, the individual answering the question has yet to see the light. He has wandered into the Church of the Blockchain, but he just didn’t realize that the man sweeping the floor is the prophet.

Here is another economics/policy question that I was asked to address at Quora. It provides great fodder for a quick Lifeboat economics review.
The US used quantitative easing to deal with one monetary crisis, and a bailout of the automotive and banking industry to deal with another. If nations, economies or individuals begin to embrace a decentralized currency, they will inevitably shift away from government issued money. Won’t this hinder a nation’s ability to intervene in a crisis?
Answering this question goes to the very heart of the ethics and politics of cryptocurrency.
Yes. Without centralized control over monetary policy, government options for intervention in a money crisis would be severely limited. But this fact may lead to a false impression…

For the same price as an international economy airline ticket, the SpaceX Starship will fly in 20 minutes what takes a normal airliner 20 hours!
I find it encouraging that so many people want to know if they should get into Bitcoin. But, I am discouraged when I discover that “getting into” is a euphemism for investing, trading, flipping or HODL (Buy, then hold on for dear life).
Sure, Bitcoin is deflationary. If widely adopted, it is likely to increase in value. But adoption is being thwarted by traders. Today 95% of cryptocurrency transactions are by individuals or organizations buying or swapping cryptocurrency rather than using crypto to buy apples, a new car, or a family vacation.
Many people consider Bitcoin to be risky and not just as an investment! They think its risky to use a payment instrument. The perception of risk is associated with its widely fluctuating exchange rate. In the end, the exchange value won’t matter at all, because Bitcoin will be the money and not the dollar, yen, euro or pound. But, unfortunately, even though the argument for widespread adoption is compelling, it will not occur while we continue to see spikes and plunges on a graph.

The title of this post is intentionally misleading. We frequently discuss the traits that lead to value here in the Lifeboat Blog. But today, I was asked a more nuanced question: “What things will hold their value?”
And there is a ulterior motive in being a columnist for Lifeboat. Analyzing the dynamics of durable value leads to some surprising conclusions about the money supply and what a society chooses to use as money. We’ll get to this at end of this post.
We know that value comes from supply and demand. There are no exceptions. But, we have not addressed the properties that make an asset hold value over the long haul. Let’s consider some examples…
Cars

But now much of the coast is covered in heaps of rotting seaweed, contributing to an economic and ecological crisis.
The issue has been caused by an enormous bloom of sargassum algae, which washed ashore from the nearby Sargasso Sea. There has long been sargassum in that part of the ocean. But the rate of its growth has increased rapidly in recent years – so much so that in 2018 its summer bloom almost spanned the Atlantic from West Africa to the Caribbean.
And things are set to get even worse.
