Im a little surprised by the techno-optimism shown by some people here (just a little, since it always shows up in this kind of debates).

Thinking/saying that technology will save us, but failing to show any succesful examples occuring today is just plain faith. Nuclear is not making progress. In fact, its the contrary: all the new, more recent nuclear plants have ended being way more expensive to build than initially predicted, and its construction has also taken way more time than initially predicted. Fusion, torio and many other experimental reactors haven't been able to move from the experimental phase to the commercial/general use market for years. Green energy can substitute part of the energy provided by fossil fuels, but electricity (it's main outcome) is just a small part of the energy we consume today (and there are many sectors where green energy simply doesn't have the power to make them work, mainly heavy industries but also transport, where it's impossible to have enough materials and batteries to sustitute the current number of fossil powered cars, buses, trucks, etc. Not counting on how expensive electric cars are, and how expensive would be to pay for the electricity needed to charge them on a day to day use, specially given the actual Kw/h prices. Neither counting how many rare materials/earths are needed to make these cars batteries and chips: there's simply not enough for a full substitution of all cars currently used). BTW, we all know that, in order to make the devices that produce green, renewable energy, we still need fossil fuels to power the machines that produce them, right? And the era of cheap oil is rapidly leaving. Coal? You know that coal is the most polluting of all fossil fuels, right? Even if, as is happening, we start burning coal again, that will only worsen the environamental and climate crisis and move our civilization collapse early. Hydrogen? It's already proven to be too expensive to produce, since it's not an energy source you can find in nature, like oil or wind: in order to produce Hydrigen you need to break H2O through electrolisis, a process that already needs energy to success. in other words: you spend more energy produccing Hidrogen than what you get from burning it, so its not efficient nor cheap. Simple thermodynamics!

No one has yet explained why if as long as there's demand there will be supply, PS5, XBSX and NSOLED are still strugglin' (A LOT) to get to shelves, with the bosses of their companies saying that production constrains will persist, at least, until 2023 (And they said that even before the Russia/Ukraine war started!).
