[quote:Anonymous Coward 75397213:MV8zNjA4MzQ1XzY0NDI0MDQwX0YyNzg4Qjc2] I can name a few since 1990: - Solid state light amplification, with EDFA (Erbium Doped Fiber Amplifier). Allowed laser photon regeneration and allowed current worldwide fiber optic network, using one EDFA per 100 Km up to 1000 Km. - Ultra high speed at Internet by using Hardware instead of software for IP switching at routers. 100's of Terabits/sec - Fractal antennae, embedded at every mobile phone, wich allow wideband reception and transmission far from the head! - Home banking, e-commerce, social media (a shame, but still). - Positron emission tomography (PET), to search full body for diseases. - Molecular composite materials, allowing different coatings being used at clothes, construction, aluminum, painting, airplanes, seats,..... - Replacement of aluminum by cooper at the junction between chips and external leads, wich allowed the creation of Gigaherts CPUs (from P4, thanks to IBM). - DirecTV and equivalent, with Galaxy V class satellites and 25" antenna. This one has to be credited 100% to Hughes. - Flat screens: Several technologies. - Ion-Lithium batteries. There are a lot of things, not visible by people, under the hood. [/quote]
Original Message
Have humans now learned everything and stopped advancing?
I dont consider self driving cars or new models of CPUs or phones as new inventions as they are just modifications of existing products.
Same A/C power since Tesla invented it. Same wireless since Tesla. Same cars since Ford. Same airplanes. Same CPUs. Same transistors. Same rocket engines. Same robots. etc, etc, etc,
Yes, they all have gotten more perfected over time but nothing is new.
