The very design of the Internet is just a bunch of interconnected servers, and search engines just consolidate access to that. I don't need that to reach my bank, or pay my bills online, or even to find code I'd like to use. They make it easier, sure, but name one site you go to that doesn't have its own localized search built-in? My grandmother just needs to know how to do the things she needs to do, and that all works fine for her. My friend spends hours just link hopping on Wikipedia for no reason. My neighbor wants to find the best deals on whatever new thing he wants to buy, okay, you'll probably need a search engine for that. Different use-cases.

Your writeup is presupposing that everyone NEEDS the latter kind of usage on the Internet, and that just isn't the case. The use of a search engine is totally optional when you're describing the Digital Divide, which is more about access to information and services being a human right. I don't think the founders of that concept had Netflix and Amazon shopping in mind.
