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.
