Yeaah and there are so many tech products that have only become a reality in the last 20 or so years. Robot vacuums, consumer 3D printers, LED lights, batteries that actually hold a useful enough amount of power for high power devices which actually even our phones are. Crazy that my phone is ridiculous amounts faster than the first computer I used, yet it lasts a full day on single charge. People take all of this and more for granted.
