“Humanity is not perfect, but it’s all we’ve got,” the SpaceX and Tesla boss said.

To safeguard human life requires moving beyond the blue planet, in Musk’s view, because earth is likely to become uninhabitable.

“There will be some eventual extinction event” if humans stay on earth forever, Musk said in an article published in academic journal New Space, which was published online in June 2017.

A being that can consciously alter its own DNA via technological intervention (i.e. cybernetic means) is what our Second Womb has been nurturing. We have used civilization to protect ourselves while we crack the code of our biological being. We started in the womb of the cave. Then moved on to the womb of the hut. Then the village, the city, and the state. All thew hile, we have been tinkering with our own DNA and the DNA of other species. To me, this is the real posthuman or transhuman — it is the creature that is actively editing its own biological blueprint through tech. This is what we’ve been doing since we started augmenting our bodies with clothing and animal skins. We’ve been modifying our ability to endure the slings and arrows of the cosmos.


What is human civilization? It is difficult to assert that other animals do not create their own civilizations — termites for instance meet some criteria for being categorized as cyborgs (building temperature-controlled mega structures). Animals communicate, express feelings, and have personalities. Octopi arrange furniture for would-be mates. Others engage in mating rituals. Some mourn the dead. Birds can solve simple math. Critters scheme, enterprise, forge bonds, and even produce art. What do we do that animals do not?

To our credit, we are the only animals that record, share, and develop history upon structures and materials outside of our bodies. We harness energy for massive projects. We farm, but again, so do leaf-cutter ants. But we create genetically novel vegetables and animals. We alter the global climate. Our enterprises are global, and given time and opportunity, our projects will eventually become exostellar. We do all this rather ferociously. Human history is a rather short explosion of civilization-building activities, and yet it might already have irrevocably altered the future of all life on this planet. No other creature has created a circumstance quite like that of human beings and our anthropocene project. For instance, unless we clean up the environment, the next few generations of plant and animal life are going to have be extremely resilient to radiation, Styrofoam, plastics, and other run-offs squeezed out from the human project. That is just a fact of life now on earth.

When a massive saltwater ocean was found hidden beneath the icy crust of Saturn’s moon Enceladus back in 2015, astronomers were cautiously optimistic that this watery world could have just the right conditions to host life. Now, thanks to a new study, Enceladus’ stock has gone up — way up.


Using data from a dead spacecraft, an international team of astronomers has for the first time discovered complex organic (carbon-containing) molecules — the building blocks of life — spewing from Enceladus. The new finding, described in a paper published online June 27 in the journal Nature, makes the small icy moon the most promising place beyond Earth to find life in the solar system.

“Enceladus’ subsurface ocean is a habitable place. The big question is if it is inhabited,” Frank Postberg, a planetary scientist at the University of Heidelberg in Germany and the study’s lead author, told NBC News MACH in an email.

For the first time, astronomers have directly observed the magnetism in one of astronomy’s most studied objects: the remains of Supernova 1987A (SN 1987A), a dying star that appeared in our skies over thirty years ago.

In addition to being an impressive observational achievement, the detection provides insight into the early stages of the evolution of supernova remnants and the cosmic magnetism within them.

“The magnetism we’ve detected is around 50,000 times weaker than a fridge magnet,” says Prof. Bryan Gaensler. “And we’ve been able to measure this from a distance of around 1.6 million trillion kilometres.”

I get this question a lot. Today, I was asked to write an answer at Quora.com, a Q&A web site at which I am the local cryptocurrency expert. It’s time to address this issue here at Lifeboat.

Question

I have many PCs laying around my home and office.
Some are current models with fast Intel CPUs. Can
I mine Bitcoin to make a little money on the side?

Answer

Other answers focus on the cost of electricity, the number of hashes or teraflops achieved by a computer CPU or the size of the current Bitcoin reward. But, you needn’t dig into any of these details to understand this answer.

You can find the mining software to mine Bitcoin or any other coin on any equipment. Even a phone or wristwatch. But, don’t expect to make money. Mining Bitcoin with an x86 CPU (Core or Pentium equivalent) is never cost effective—not even when Bitcoin was trading at nearly $20,000. A computer with a fast $1500 graphics card will bring you closer to profitability, but not by much.

The problem isn’t that an Intel or AMD processor is too weak to mine for Bitcoin. It’s just as powerful as it was in the early days of Bitcoin. Rather, the problem is that the mining game is a constantly evolving competition. Miners with the fastest hardware and the cheapest power are chasing a shrinking pool of rewards.

The problem arises from a combination of things:

  1. There is a fixed rate of rewards available to all miners—and yet, over the past 2 years, hundreds of thousands of new CPUs have been added to the task. You are competing with all of them.
  2. Despite a large drop in the Bitcoin exchange rate (from $19,783.21 on Dec. 17, 2017), we know that it is generally a rising commodity, because both speculation and gradual grassroots adoption outpaces the very gradual increase in supply. The rising value of Bitcoin attracts even more individuals and organizations into the game of mining. They are all fighting for a pie that is shrinking in overall size. Here’s why…
  3. The math (a built-in mechanism) halves the size of rewards every 4 years. We are currently between two halving events, the next one will occur in May 2020. This halving forces miners to be even more efficient to eke out any reward.
  4. In the past few years, we have seen a race among miners and mining pools to acquire the best hardware for the task. At first, it was any CPU that could crunch away at the math. Then, miners quickly discovered that an nVidia graphics processor was better suited to the task. Then ASICS became popular, and now; specialized, large-scale integrated circuits that were designed specifically for mining.
  5. Advanced mining pools have the capacity to instantly switch between mining for Bitcoin, Ethereum classic, Litecoin, Bitcoin Cash and dozens of other coins depending upon conditions that change minute-by-minute. Although you can find software that does the same thing, it is unlikely that you can outsmart the big boys at this game, because they have super-fast internet connections and constant software maintenance.
  6. Some areas of the world have a surplus of wind, water or solar energy. In fact, there are regions where electricity is free.* Although regional governments would rather that this surplus be used to power homes and businesses (benefiting the local economy), electricity is fungible! And so, local entrepreneurs often “rent” out their cheap electricity by offering shelf space to miners from around the world. Individuals with free or cheap electricity (and some, with a cold climate to keep equipment cool) split this energy savings with the miner. This further stacks the deck against the guy with a fast PC in New York or Houston.

Of course, with Bitcoin generally rising in value (over the long term), this provides continued incentive to mine. It is the only thing that makes this game worthwhile to the individuals who participate.

So, while it is not impossible to profit by mining on a personal computer, if you don’t have very cheap power, the very latest specialized mining rigs, and the skills to constantly tweak your configuration—then your best bet is to join a reputable mining pool. Take your fraction of the mining rewards and let them take a small cut. Cash out frequently, so that you are not locked into their ability to resist hacking or remain solvent.

Related: Largest US operation mines 0.4% of daily Bitcoin rewards. Listen to the owner describe the effiiency of his ASIC processors and the enormous capacity he is adding. This will not produce more Bitcoin. The total reward rate is fixed and falling every 4 years. His build out will consume a massive amount of electricity, but it will only grab share from other miners—and encourage them to increase consuption just to keep up.


* Several readers have pointed out that they have access to “free power” in their office — or more typically, in a college dormitory. While this may be ‘free’ to the student or employee, it is most certainly not free. In the United States, even the most efficient mining, results in a 20 or 30% return on electric cost—and with the added cost of constant equipment updates. This is not the case for personal computers. They are sorely unprofitable…

So, for example, if you have 20 Intel computers cooking for 24 hours each day, you might receive $115 rewards at the end of a year, along with an electric bill for $3500. Long before this happens, you will have tripped the circuit breaker in your dorm room or received an unpleasant memo from your boss’s boss.

  • Professional mining pool (above photo and top row below)
  • Amateur mining rigs (bottom row below)

This is what you are up against. Even the amateur mining operations depicted in the bottom row require access to very cheap electricity, the latest processors and the skill to expertly maintain hardware, software and the real-time, mining decision-process.
