    This is incredibly inspiring! The way AI can transform our energy crisis into an opportunity shows us that every challenge holds the seeds of innovation. We have the power to create a sustainable future – let’s embrace it with optimism and action! 💡

    How about we stop inventing unnecessary catastrophic problems that need to be solved and actually address real problems in real life?

    And Ted, inviting used car salesman to your platform isn’t helping anyone

    This guy sounds like he doesn’t have any idea about actual energy production. You can’t just generate with full capacity at all time. It’s not even about the production cost . It never was about that. The problem was emissions. Even if the grid can take such a prolonged hit and pressure, this will break every thing around and associating with it. And in the end what he say its like yeah this poison can actually cure your cancer. By killing you faster. These guys are calling their short term get rich scheme a solution to fantasy of infinite growth money tree. Freaking delusional

    This is a sales pitch, not education. Smart grids have been a partially implemented idea for a long time. Undervolting and redundant server space in different locations isn’t a revolutionary idea.

    It can solve its own energy crisis. By not draining those resources dry to begin with. There, I fixed it. Can I give a TED talk now? It would be demonstrably better than all the snake oil you’ve been pushing lately.

    The more I see and work with AI the more I think it is going to eat itself. No software has ever quite lived up to it’s hype. Even years in. AI is going to take this misfire harder and faster than most realize. Even simple food service programs don’t work. They drive customers away. Workers don’t have time to train or the knowledge to fix AI issues. AI cannot fix its own problems. Very quickly more and more people will begin to distrust everything AI. AI doesn’t know its giving you bad information because it can’t process real truth. It is already wrecking social media. You can no longer trust anything you see on TikTok, Facebook, Instagram, or other social media. People want to connect with other humans but AI is eliminating that connection. Once people realize nothing is true on social media they will find other ways to pass the time. It is already happening. AI is stupid intelligence because it simply draw information from sources it has no idea are true or real. It is garbage in, garbage out in an autonomous algorithm.

    What a load of AI hype bullshit, If AI was any good it would completely switch itself off, rather than wasting energy. These AI proponents are still not delivering things of value, it’s all just playing the market to get some investment. Time to start realising this and switch it off. I work in this area, and I know very few people who think differently. This guy is a bullshitter, and that TED is ramming this crap down peoples throats is dispicable.

    • @the_stixXx

    All this Ai crap is just that, crap.
    It’s not going to allow us to be independent and wealthy and not need to work, that’s only for those that are already rich. It’s already replacing people by taking jobs, ruining creative brains and hurting humanity.
    My son is 14 and he hates Ai. He refuses to adopt it. I think that is beautiful, but I also think it could hurt him because we live in a world that if you don’t stay on the forefront of what is driving everything, you end up making it harder on yourself.
    Can we go back to the late 80s and early 90s please.

    Should Young People Start Working Early?

    Introduction
    Some people believe that young people should start working while they are still in school, while others think they should focus only on their studies. This essay will discuss both views and give a balanced conclusion.

    Body 1
    Starting work early has several benefits. Teenagers learn responsibility, time management, and financial skills. Working part-time also gives them real-life experience that can help them choose a future career. Many young people feel more independent when they earn their own money.

    Body 2
    On the other hand, having a job can distract students from their studies. Schoolwork requires time and energy, and part-time jobs might lead to stress or lower grades. Some teenagers may even give up their education if they become too focused on earning money.

    Conclusion
    In conclusion, working early can be useful for young people, but it should not interfere with their education. The best option is for students to work only a few hours per week while keeping school as their main priority.

This week’s guest is Ayal Yogev, co-founder and CEO of Anjuna Security, who has experienced both sides of the startup journey: scaling quickly during the boom years and then making the incredibly difficult decision to lay off a significant portion of his team when the market shifted.

From growing to 75 employees to scaling back and rebuilding, Yogev learned firsthand that the hardest part of leadership isn’t hiring fast, it’s making tough decisions with care, transparency, and integrity.

In this episode, Isabelle Johannessen and Yogev unpack what it really means to lead through layoffs with compassion and how founders can support their teams even in the most challenging moments. They also explore the lessons learned from scaling too quickly and how to build a more resilient company the second time around.

Apply to Startup Battlefield: We are looking for early-stage companies that have an MVP. So nominate a founder (or yourself): techcrunch.com/apply. Be sure to say you heard about Startup Battlefield from the Build Mode podcast.
