"The most compelling reason for most people to buy a computer for the home will be to link it into a nationwide communications network. We’re just in the beginning stages of what will be a truly remarkable breakthrough for most people—as remarkable as the telephone."

"With Web-based software, most users won't have to think about anything except the applications they use. All the messy, changing stuff will be sitting on a server somewhere, maintained by the kind of people who are good at that kind of thing. And so you won't ordinarily need a computer, per se, to use software. All you'll need will be something with a keyboard, a screen, and a Web browser. Maybe it will have wireless Internet access. Maybe it will also be your cell phone. Whatever it is, it will be consumer electronics: something that costs about $200, and that people choose mostly based on how the case looks. You'll pay more for Internet services than you do for the hardware, just as you do now with telephones."
Jobs' observations seem spot on and they are, but I think this was already in the consciousnesses for the industry at that time. It only seems out there compared to what "regular people" outside the niche would have said. Or possibly to those of us who are too young to remember the kind of attitudes you'd hear in the 80s. (I barely remember this, but it was definitely there...)
Your pg quotes are also notable for what they got wrong. I read that as a "web browser as dumb terminal" view - not unconventional for its time. As we've seen, first with JavaScript and then with mobile apps instead of the browser, complexity in the client and running code locally is still a good thing. For many tasks the web has lost.
The story of the birth of the internet is an interesting one that had little to no involvement from guys like Jobs, who were fixated on the new desktop market and were shockingly short-sighted in regards to networking. When did we even have an integrated by default modem in the 80s? The desktop guys talked a big game regarding the future, but knew their bread was buttered by hardware and software sales and this whole dial-up thing wasn't profitable for them. In fact, it was kinda a threat. I spent a lot more time playing things like Tradewars (or other doors games) or MUDs, for free, than buying the AAA titles of the time, which I found boring because they couldn't do online multiplayer.
But we shouldn't elevate it to something it's not. The cynical view, and to an extent a correct one, is that this is 1980s conventional wisdom mixed with a guy trying to sell computers.
1984.

Which wasn't a huge prediction; CompuServe's consumer offering had been available for years (and they had at least one smaller national competitor, The Source), and the BBS scene including BBS networks was already a thing. The value of computers as communication devices especially in a network with wide penetration wasn't something that the many observers at the time who made similar comments were extrapolating from scant evidence, its something that people had concrete experience with in the mid-1980s where the trend toward it becoming a key use of computers was widely recognized in social commentary, fiction, etc.
