Elon Musk Says That Within Two Years, AI Will Be “Smarter Than the Smartest Human”

Posted by in categories: Elon Musk, humor, robotics/AI

Tesla CEO Elon Musk — who has an abysmal track record for making predictions — is predicting that we will achieve artificial general intelligence (AGI) by 2026.

“If you define AGI as smarter than the smartest human, I think it’s probably next year, within two years,” he told Norway wealth fund CEO Nicolai Tangen during an interview this week, as quoted by Reuters.

The mercurial billionaire also attempted to explain why his own AI venture, xAI, has been falling behind the competition. According to Musk, a shortage of chips was hampering his startup’s efforts to come up with the successor of Grok, a foul-mouthed, dad joke-generating AI chatbot.

Nash equilibrium

Posted by in categories: economics, entertainment

J. V. Neumann, Zur Theorie der Gesellschaftsspiele, 1928. Proved the existence of equilibrium in 2 players’ zero-sum games.

The birth of game theory.

The modern concept of Nash equilibrium is instead defined in terms of mixed strategies, where players choose a probability distribution over possible pure strategies (which might put 100% of the probability on one pure strategy; such pure strategies are a subset of mixed strategies). The concept of a mixed-strategy equilibrium was introduced by John von Neumann and Oskar Morgenstern in their 1944 book The Theory of Games and Economic Behavior, but their analysis was restricted to the special case of zero-sum games. They showed that a mixed-strategy Nash equilibrium will exist for any zero-sum game with a finite set of actions.[13] The contribution of Nash in his 1951 article “Non-Cooperative Games” was to define a mixed-strategy Nash equilibrium for any game with a finite set of actions and prove that at least one (mixed-strategy) Nash equilibrium must exist in such a game. The key to Nash’s ability to prove existence far more generally than von Neumann lay in his definition of equilibrium. According to Nash, “an equilibrium point is an n-tuple such that each player’s mixed strategy maximizes his payoff if the strategies of the others are held fixed. Thus each player’s strategy is optimal against those of the others.” Putting the problem in this framework allowed Nash to employ the Kakutani fixed-point theorem in his 1950 paper to prove existence of equilibria. His 1951 paper used the simpler Brouwer fixed-point theorem for the same purpose.[14]

Polaris Dawn is getting closer and closer to being launch ready

Posted by in category: space travel

Things are slowly falling into place for the Polaris Program’s first mission, Polaris Dawn. The mission is nearing milestones that might finally give it a launch date that will actually hold.

Polaris Dawn, a private mission being paid for by Shift4 CEO Jared Issacman, who also paid for and flew on Inspiration4 in 2021. The goal of the mission is to fly higher than any human spaceflight since Apollo, perform the first private spacewalk, and conduct numerous science experiments in orbit.

Like Inspiration4, Polaris is partnering with SpaceX to complete this. Currently, SpaceX is the only company capable of this sort of feat. To do so, the company has modified its Dragon spacecraft to support spacewalk operations and develop an upgraded spacesuit to be used in the vacuum of space.

Tesla is laying off more than 10% of its workforce, memo shows

Posted by in categories: Elon Musk, sustainability, transportation

Tesla is the latest major company to lay off employees.

The company is eliminating “more than 10%” of staff globally, according to an internal memo sent by Elon Musk on Sunday, which was seen by Business Insider. The layoffs have come shortly after the carmaker posted lackluster delivery numbers.

Musk wrote in the email: “There is nothing I hate more, but it must be done. This will enable us to be lean, innovative and hungry for the next growth cycle.”
