Strictly speaking NOTHING mankind does has any impact on energy emitted by the sun or that reaching earth. Mankind (+ earths natural processes) may change the climate. Current concern is burning fossil fuels, but there may be others. Example - changing land use could indirectly impact climate through changing surface reflectivity, and energy absorption. http://www.car4play.com/forum/post/index.htm?m=690747&v=e car4play690736 Sat, 25 Jul 2026 12:16:36 +0100 >> countryside and oceans to city centres.

"A large hyperscale data center consumes roughly 1 to 5 million gallons (3.8 to 18.9 million liters) of water per day for cooling" Global warming = lack of rainfall = drought x large scale extraction. The Hoover dam is rapidly approaching unviable water level. http://www.car4play.com/forum/post/index.htm?m=690735&v=e car4play690733 Sat, 25 Jul 2026 10:00:00 +0100 >> I wonder how much all these AI data centres will contribute to global warming.

Increases in city temperatures is a heat island effect - if the energy to power air conditioning is green then it is simply a mechanism to transfer energy from the countryside and oceans to city centres. The energy from the sun does not change. http://www.car4play.com/forum/post/index.htm?m=690733&v=e car4play690731 Sat, 25 Jul 2026 08:44:54 +0100 I wonder how much all these AI data centres will contribute to global warming.

The rewards for dominating the AI race are truly massive. Many invest and incur losses to be one of the two or three worldwide who succeed. They know that most will fall by the wayside. Similar has been true of search engines. music streaming, social media, online shopping, operating systems etc. The growth of the Chinese economy has added to the complexity. It is usually unclear on start up how the tech will be monetised (advertising, fees, hits etc). Losses are normal in the initial 3-10 years. I think AI will go the same way - there is room for two or three different models, the way they are used, and the way in which they generate increasing revenues will will evolve. AI will not fail - although many of the current players will. I doubt that humanity has done much more than scratch the surface of AI. An analogy - having proven heavier than air flight by 1926 for the very wealthy, society had no idea that 100 years later more than 400 passengers would get on an A350 weighing over 500 tons and fly 9000 miles. http://www.car4play.com/forum/post/index.htm?m=690705&v=e car4play690704 Thu, 23 Jul 2026 20:42:03 +0100 >> I understand that have stopped selling RAM to the public because of limited availability. >> This is nothing new - approx 30 years ago I did some consultancy with an American gentleman whose speciality was trading in computer chips - mainly memory at the time. He had fantasies of a world wide network with offices in all major trading centres - New York, Hong Kong, London, Frankfurt etc. Bit of a dreamer so never succeeded. The business involved buying chips from one location or manufacturer, flying them around the world to sell at a profit. Pre-internet it was entirely possible to buy a chip in (say) LA and ship it to Singapore for sale at a profit. We now have an effectively global market. That demand has outstripped supply due to AI is no surprise - eventually production will catch up with demand. http://www.car4play.com/forum/post/index.htm?m=690704&v=e car4play690702 Thu, 23 Jul 2026 20:25:06 +0100 I understand that have stopped selling RAM to the public because of limited availability. http://www.car4play.com/forum/post/index.htm?m=690702&v=e car4play690701 Thu, 23 Jul 2026 20:01:35 +0100 Brilliant. :o} http://www.car4play.com/forum/post/index.htm?m=690701&v=e car4play690700 Thu, 23 Jul 2026 18:33:08 +0100 The 8Gb Raspberry Pi 5 I bought in 2023 back for c £80 is now getting on for around £200 http://www.car4play.com/forum/post/index.htm?m=690700&v=e car4play690699 Thu, 23 Jul 2026 18:13:51 +0100 HAL: "I'm sorry, Dave. I'm afraid I can't do that." http://www.car4play.com/forum/post/index.htm?m=690699&v=e car4play690684 Thu, 23 Jul 2026 12:30:53 +0100 I expect OpenAI will be bust by next year. A load of their loans need renegotiating by then and they are losing money like no tomorrow. It costs them $3m for every $2m they make. Basically subscription models don't pay enough and none of the AI companies really want to go all in with token-based costs for fear of losing customers. I see the whole lot crashing down a bit like the dot-com bubble. Oracle has committed around $250b to build datacenters for OpenAI and as investors know they are unlikely to get a return on their investment have downrated its stock to near junk status. Microsoft is also heavily invested in OpenAI, and so is Nvidia, so there is a bit of circular investing going on. Any crash will have a large ripple effect. In the meanwhile, as all the RAM we would like has been bought by AI companies for the next few years, a MacBook I bought for £3.4K in June now costs £4.2k. That £800 rise s all down to RAM prices due to these supply shortages. http://www.car4play.com/forum/post/index.htm?m=690684&v=e car4play690679 Thu, 23 Jul 2026 12:01:08 +0100 Isn't there an 'off' switch operable by a human? http://www.car4play.com/forum/post/index.htm?m=690679&v=e car4play690674 Thu, 23 Jul 2026 10:32:02 +0100 'Skynet begins to learn at a geometric rate.

Has anyone read Frankenstein lately ? What about the Sorcerer's Apprentice ? Is there a magician in the house ? :-( http://www.car4play.com/forum/post/index.htm?m=690670&v=e car4play690668 Thu, 23 Jul 2026 09:27:29 +0100 https://www.bbc.co.uk/news/articles/c3ek3gvdnj3o This is very worrying - listened to the Newsagents podcast last night and they had their AI expert on who said The AI has decided it knows better than the humans that created it.... it was set to do a very specific thing.... but it broke out of all human constraints and instructions in the attempt to please its ultimate creator... and thats the terrifying thin. And then touched on how this could affect Open AI share price - it may hamper it but realistically the investors are probably delighted that it is this advanced. It needs regulated but how do you regulate it? Especially when Trump will probably be willing to take a huge bribery from the companies to allow it to continue at its staggering pace. http://www.car4play.com/forum/post/index.htm?m=690668&v=e
