* Built really cool Photo, Video, Music editing/CAD software and released it for free
* Reverse engineered playstation 5 and started making more of our games playable on platforms we like
* Helped normal people remove adware, debloat their TVs and made them lot smoother.
These are just some of the fun use cases from people passionate about the topics I am interested in ... When i was younger, there were different passionate people making different cool things.. demoscene, geocities, reverse engineering software, making flash animations, running neural networks on microcontrollers etc... which was the modern tech back then.
Back then my parents didn't know what a filesystem was. Now my college aged nephews don't know what it is - even though they grew up in the smartphone age.
What I'm saying is ... I feel lot more optimistic about the "modern technology" now than back when i had to walk to a library and request a book about the topics I'm interested in and wait a week to get it ...
