  • I personally think it will take a complete shift in human mentality. One that will only come about via artistic movements, whether that be music, painting, film, or even propaganda posters.

    IMO, art is the most important factor for bring about such a massive cultural shift. Kind of like how art in the Renaissance caused people to view life more scientifically and logically instead of based purely of faith.

    Similarly, art from the the hippie movement in the 70s promoted peace and love instead of competitiveness, war and destruction.

  • These models always assume that direct carbon capture technologies will extract ridiculous amounts of the CO2 out of the atmosphere.

    Also 3C will be devastating as is though. That's not including biodiversity loss, ocean acidification, and rising sea levels.

  • Probably via some attempt to force everyone to verify who they are online by providing their identification documents. It will probably be managed by some company specialized in handling that data, and of course willing to share the data with police and other gov organizations. Data that will be used to track citizens.

    Just another endless battle to keep net neutrality alive.

  • As someone who does R&D testing on plastics that are used in medical devices, I have some insight. Of course the type of plastic matters, but all plastics use carcinogenic chemicals during the manufacturing/extrusion process.

    To make most plastic, a polymer resin is mixed with additives such as solvents, plasticizers, and stabilizers at high temperatures. Ideally, you want the additives to evaporate out during production so that you're left with just the newly formed plastic.

    But some of these additives get trapped in tiny air pockets between polymer chains. When they're reheated, the polymer chains relax and release the volatile, carcinogenic additives into the air.

    This is likely where the toxicity is coming from, not the polymer chain itself. So regardless of the type of plastic used, reheating the polymer during 3D printing will release some volatile additives.
