Deep learning is one of the best technological advancements having numerous applications which leverage the neural network features for projects like neural enhance and the controversial face-swap technology used in deepfake videos.
Can humanity become a Type I civilization without causing our own Great Filter?
Can humanity become a Type I civilization without causing our own Great Filter?
There are several ways we can measure the progress of human civilization. Population growth, the rise and fall of empires, our technological ability to reach for the stars. But one simple measure is to calculate the amount of energy humans use at any given time. As humanity has spread and advanced, our ability to harness energy is one of our most useful skills. If one assumes civilizations on other planets might possess similar skills, the energy consumption of a species is a good rough measure of its technological prowess. This is the idea behind the Kardashev Scale.
Russian astrophysicist Nikolai Kardashev proposed the scale in 1964. He categorized civilizations into three types: planetary, stellar, and galactic. A Type I species is able to harness energy on a scale equal to the amount stellar energy that reaches its home planet. Type II species can harness energy on the scale of its home star, and Type III can harness the energy of its home galaxy. The idea was further popularized by Carl Sagan, who suggested a continuous scale of measurement rather than simply three types.
So what type of civilization are we? Although humans use a tremendous amount of energy, it turns out we don’t even qualify as Type I. About 1016 Watts of solar energy reaches Earth on average, and humanity currently uses about 1013 Watts. On Sagan sliding scale, that puts us currently at about 0.73. Not bad for a bunch of evolved primates, but it raises an interesting question. Could we even reach Type I? After all, we can’t capture all the sunlight that reaches Earth and still have a habitable planet.

The company’s board and the Tesla CEO hammered out the final details of his $54.20 a share bid.
The agreement marks the close of a dramatic courtship and a sharp change of heart at the social-media network.
Elon Musk acquired Twitter for $44 billion on Monday, the company announced, giving the world’s richest person command of one of its most influential social media sites — which serves as a platform for political leaders, a sounding board for experts across industries and an information hub for millions of everyday users.
The acquisition followed weeks of evangelizing on the necessity of “free speech,” as the Tesla CEO seized on Twitter’s role as the “de facto town square” and took umbrage with content moderation efforts he has seen as an escalation toward censorship. He said he sees Twitter as essential to the functioning of democracy and said the economics are not a concern.
Ownership of Twitter gives Musk power over hugely consequential societal and political issues, perhaps most significantly the ban on former president Donald Trump that the website enacted in response to the Jan. 6 riots.
The successful all-private visit to the International Space Station paves the way for future flights.
What if we could use a hydrogen molecule as a quantum sensor in a terahertz laser-equipped scanning tunneling microscope? This would allow us to measure the chemical properties of materials at unprecedented time and spatial resolutions.
This new technique has now been developed by physicists at the University of California, Irvine, according to a statement released by the institution on Friday.
“This project represents an advance in both the measurement technique and the scientific question the approach allowed us to explore,” said in the press release co-author of the new study Wilson Ho, Donald Bren Professor of physics & astronomy and chemistry.
