8. "Google Reader was amazing and I still think about it like once a week. I really enjoyed that platform."
9. "I feel like 3D printing was advertised as AI-level transformation about 12 years ago. I remember guys at my work investing in stocks. I know people use it and innovate with it, but it didn’t seem to change the landscape as radically as advertised."
