What if we could have AI and *not* harm the planet? #TEDTalks

Artificial intelligence is changing everything — but at what cost? AI sustainability expert Sasha Luccioni exposes how tech companies’ massive data centers are burning through energy and wrecking the planet. She introduces a powerful alternative: small but mighty AI models that could flip the script and make the technology smarter, fairer and sustainable.

    I agree, 100% 👍

    The big tech companies are already incentivized to get power and costs down. It’s going to take a massive Investment, I would suggest it’s more of a short term pain for a long term gain .

    AI must be contained/regulated.

    AI is more of a danger to mankind than climate change.

      Not to mention how heavily it contributes to climate change….Data centers using energy and water at catastrophic rates…

      AI will most likely create a virus that wipes us all out.

    This is what it sounds like when there is money to make. MF, please! The sake of our planet left to rely on AI because not so good people have so much money they’re becoming way to big and lazy and now want to be isolated amongst each other and dominate even more with an iron hand; inevitably.
    As of now AI is being verbally sold to you and if enough people buy in around the 🌎 then it happens but were beyond that point already.

    Sounds like having to find an immediate and urgent solution to a massive problem that we created ourselves. Who could have seen that coming? 🤔

    Does this person know anything about neural networks or just doesn’t like people expressing their freedom the way they want? Freedom to research or freedom to solve issues however people want? Don’t like AI? Me too. Let’s just avoid using it for this matter. Why you want to always use government to regulate things?

    • @PranavBatra-l4y

      December 28, 2025 at 5:13 pm

      You make a good point man, but it’s even bigger than that. I fear it will be too late before humanity(not just government and/or tech giants) strikes the perfect balance between regulation and autonomy.

    Return power to the regulators…ie the government. This sounds like a left wing advert for communism

    • @basicisaac

      December 29, 2025 at 3:15 am

      So the current government in the USA is communist? Trump and Putin are all communists, that’s what you’re saying?

    AI is better suited to replace executives and politicians rather than workers.

    What if I was tall and short. What if I was dumb and smart. What if I was, you get my point. This person isn’t solving anything!

    Very nice “what”, but really missing the “how” in a practical sense.
    I mean, we can use local LLM’s which are already publicly available. The downside is that in order to get a timely response, you will need some decent hardware, which has higher power consumption. So just switching to that would decentralise power consumption, but have it used nevertheless. As you’re probably not using it 24/7, having it local would already be 1/3 overhead for sleep alone. So decentralised local LLM’s would probably have a 10% efficient use, meaning we would have 90% overhead. This just proves the value of centralised AI hubs(datacenters) that can achieve much higher efficiency. Since in a country like the Netherlands, datacenters consume over 4% of the national power, MS and Google alone about 2%.
    What we do need to do is to give such datacenters incentives to reduce power consumption drastically. Not only will this already improve the current situation, it will also lay the groundwork for more energy efficient AI in a decentralised way in the long run.

    AI uses very small power, like loading a web page, to answer a query. It takes lots of power to create the model initially only.

    I used AI for a while and it basically took a lot of time from me, kost a lot of energy and money and what it gave back wasn’t of much relevance.
    People use AI for recipies and jokes not because of carelessness, but because it is not of much use for anything else.
    Any meaningfull usage requires you to check, troubleshoot and re-check the result over and over again until you wasted time and money with no creative or meaningfull result.
    I postulate: Most of the things AI can do are not important, not meaningful in the first place.
    Instead of using AI to bloat up needless text and create more of it we should focus on make things that are meaningfull and creative.
    AI only saves time doing things that were meaningless in the first place.
    Most importantly we should minimize the time we spend with needless texts like formalities and courtesies we don’t mean and concentrate on things that are meaningfull, creative, true and come from us.
    AI is not helping. It costs a lot and produces nothing of worth.

    I love the polarity in people’s opinions. Some are hopeful, some of filled with fear. While I get both, what good does worrying do? We HAVE to use the tools and not let them be our master. Yet some will still give their power away bc they feel weak/slow/stupid anyway even when we’re shown a way thru.

    You thinking in right direction they should give public the access to make it better just like memes if developers will get access it will improve people are really creative these days they will surely improve it
