> I miss the optimism and feeling of limitless potential that existed around technology
Having grown up along with the Internet, I feel this is a common sentiment among those who experienced the early days when things were just getting started. It seems we're losing touch with the vision and culture that gave birth to this technology and made it seem magical, like participating in a collective evolution.
The commercialization of the Internet and the shared space it enables is a symptom of modern social priorities (as a sibling comment pointed out). It's part of the history of colonization of all public space and the public themselves. As one of the "natives", it's hard not to feel cynical about the transformation - but that, at least for me, ties in with a deeper cynicism about society and its values, the direction of culture and civilization.
On a more positive note, there's a kind of generational knowledge transfer, passing the torch: the history, the set of values, the original insights that formed the foundation are all (or much of it) still there, being taught/learned, carried on, elaborated and pursued further. As I get older, I feel more responsibility to play my part, to do what I can in my local sphere of influence. That also opens my eyes to what others are doing in terms of activism and education.
