    if we are seeing past from JWST then why are we people spends Billions of dollars to see life or water on other planets when it is already in the past like mars and also we can’t reach or neither if we can reach there would be extinction because we were seeing the past from JSWT not present.😂

    giving a speech at toastmasters club tomorrow and i came here looking for a speech which would help me understand how to not tense up like i naturally do during speeches. this being their most recent post showed up on top and i’m really glad because not only is this interesting, she delivers it in such a soothing tone. i aspire to be able to speak like she does!

      @ We don’t know the odds for us being here. But we do know that potentially habitable worlds (and the ingredients for life) are very common, we have many in our own solar system. Forgive me for saying, but I think it is hubristic to think we are alone in the universe, and further that it’s a hubris born out of religious anthropocentrism, and simply the need to feel special. It’s the same reason we hang on to the idea that we are the only conscious animals, when that notion is obviously false.

    I am here to answer this question: no, we are not the only intelligent creatures in the whole universe. Even on Earth, some creatures exceed our imaginable intelligence by a great margin(THERE ARE CREATURES OTHER THAN HUMANS) who know more than HUMANITY has known from the beginning of time !

    Other intelligent beings exist but are extremely far away we cannot see, let alone make contact with them. Our existence is but a blink of an eye compared to the age of the universe. We are separated by unimaginable distances and time scales, a little daunting yet so fascinating. Possibly when one civilization is just starting out, another is on the verge of extinction.

The Despacio tent is a temple of music for audio geeks, and the brainchild of LCD Soundsystem frontman James Murphy, Stephen and David Dewaele of 2manydjs aka Soulwax, and audio engineer John Klett. First created in 2013, Despacio makes its way from festival to festival, blasting dancers with vintage vinyl from seven McIntosh speaker stacks that make up the 50,000-watt sound system along with the lighting rig and iconic disco ball that complete the experience. CNET social producer Faith Chihil got a chance to catch it at Portola Music Festival in San Francisco and here’s what she found. #despacio #portolamusicfestival #festival #audiophile #vinyl

It’s not AI anymore, it’s ‘super intelligence’ (according to the White House) | Equity Podcast

This week, the White House got nearly every major tech CEO in one room — Zuckerberg, Bezos, Musk, and Anthropic’s Dario Amodei among them — to sign an AI safety pledge that President Donald Trump called “morally binding.” Trump also signed an executive order officially rebranding AI as “super intelligence,” and meanwhile, Meta and OpenAI are putting friendlier faces on their AI products, even as the biggest money in AI still appears to be coming from the enterprise.

On this episode of TechCrunch’s Equity podcast, Kirsten Korosec, Anthony Ha, and Sean O’Kane dig into this week’s AI moves, the ugly economics of consumer AI, plus the shifting IPO market and a handful of startup deals.
