For me anyway, the modern web feels like the realization of those early internet pioneering ideas. I run my own personal site, with a nice open source google photos replacement, hosting my own VDI, streaming services, you name it. It’s all running on a pile of discarded speak and spell’s in my basement (a joke but only barely, this junk will run on anything that can host a container). It’s all possible thanks to the open source shoulders of giants I’m standing on and in spite of my lack of coding experience (I’m dev/ops). The fact that I run more infrastructure than my first few jobs combined, as one hobbyist, kinda blows my formerly teenage brain.
It’s still out there, just so long as you are willing to DIY. I am holding great hope for the fediverse, although I’ve been getting used to disappointment lately.
