Here you go. Interview he did in 1999. I can't find it right now, but this isn't the full interview; he goes into a bit more detail after this and mentions the bad things it would bring that we are starting to become more well known and widespread.

I see it a little differently. I think the internet has lived up to and exceeded its potential. It’s done things we couldn’t even have thought of back in the beginning. Or course as it grew, it became no longer just the playground of academics, scientists, and creatives. It now has huge commercial regions and is as mainstream as any other medium. It’s no longer solely a cool place where cool people are doing cool things. It is now also playing a role much like television for a bunch of dumb masses to be shown commercials by corporations.

What’s worse is the unimagined downsides. Election misinformation. Hate group echo chambers. Terrorists using it to organize. We failed to imagine these things back in 1992 but maybe that really is just a failure of our imaginations, not the internet. I remember the heady dreams of democratization and universal access to quality information. It was all pretty naive. There were people who imagined television technology would be used for in-home education, too.

But the bad stuff doesn’t erase the cool stuff. It is still enabling creativity and science, arguably moreso than the halcyon days of HTML 1.0. Did any of us ever imagine in 1992 that thousands of scientists could use images from hundreds of locations around the world to construct an image of a black hole, sharing data, tools, code, and ultimately the image itself over the internet? It’s just wild. Remote surgeries, AI, self driving cars, tracker tags, home automation… it all runs on the internet. A lot of it is scary, but it’s also fascinating and far beyond what we imagined 30 years ago.

We used to talk about video conferencing like some far off future. Just because now we see it as mundane doesn’t mean the internet didn’t deliver on its potential. It delivered, and more. We just forget how cool a lot of it is, we were dumb to think it would be nothing but roses, and it’s changing life so much that it’s getting a bit scary.

But didn’t live up to its potential? Nah.

So I don’t really even see your posited problem, and this makes it hard for me to understand your point about a solution. I guess “corporations bad and no one will fix it,” is the bottom line? Well, that has nothing to do with the Internet and everything to do with capitalism. It’s the worst system there is, except all the others that have ever been tried. If you have any new ideas, we could sure use them.
