It's tough here because Google is both an ad company and a product company (funded through ads).

Would you have the same fears if Apple were able to (through some ridiculous miracle) achieve the same thing?

This might be off-base, but i think your problem is not about storing information, more about keeping all that info in your mind so you can apply it. I tend to have an itch to catalogue and store information, but it quickly reveals that the constraint is time and what I can keep in my head rather than the info i have squirreled away somewhere.

The key is to understand that organizing/filtering the relevant info is a separate task from cataloguing. I spend a little time every week doing that.

Tools -

https://workflowy.com/ - hierarchial lists, very useful! to keep track of important todos/things to remember in the week.

ultra.work/lights-generator (thats a URL) - to track habits that i want to do every day.

Filters and labels in Gmail.

Any email I send to myself is automatically marked as read... then based on what’s in the subject line a label is automatically applied. For example, if I have an idea for a design I send an email with a subject of “Design - blah blah” and whatever text in the body. The filter I set up in Gmail looks for the word “Design” in the subject, marks it as read so I don’t get notified of a new email, and then applies the Design label. From there, I usually start an email thread on that subject line as I have more ideas.

Most articles are saved to pocket. If I really like it, you can "favorite it". When I'm bored from time to time, I'll scroll through what I've favorited. A good chunk of the time I'll prune stuff I no longer appreciate.

If there's certain types of learnings that I really appreciate --> I'll add it to Anki, but just a little snippet of Q/A.

Q - How should you view SSDs when scaling high traffic sites? A - "Think of SSDs as cheap memory, not expensive disk" - This was from an article from High Scalability about Reddit.

I do almost the same thing with pocket and GitHub. I use Pocket to save articles. I slack in tagging them but sometimes sit down and tag all the untagged items at once. About going back, I have recently started taking notes from them in a Github readme so that I can just go back to the readme and find the appropriate one to see. I have only recently started doing this as the number of saved articles have become overwhelming.

It works out well, if not perfect. Usually, articles are not to be re-read completely, only the important parts or the gist is enough.

Please let me know what are your thoughts regarding this. May be we will both find a better way to deal with this.

I use tagging heavily with any note taking application (like One Note / evernote). I use voice recorder to record any useful ideas / lessons that my subconscious brain tells me. I then push it to my note taking application with appropriate tag and push it to my cloud drive. I review them once in a while.
