I think the problem isn't so much that we're running out of things to turn into consumables (that don't quickly bore us), but as you said, the parceling and abstraction of everything in the first place, that we turn things into consumables instead of ourselves into creators/gardeners of our lives and the world around us. I mean, there is still a lot of fauna to discover, and what's more, there's still a lot of living in peace with and appreciation of a lot of fauna we already know about to do. Heck, if we just let up a "little", new exciting things and interactions can occur. And one lifetime is not enough to learn about even just a small section of animals. It is possible for "humans knowing everything about lions", and me not ever even having seen a photo of one, if you know what I mean.
And then there are other people. Who could be fascinating mysteries, friends and enemies, instead of boring potential threats of resources. Of course, when the only way we relate to each other is "so what 'are' you?" (what are you mostly earning your money with at the moment), "do you know $reference, too?", "do you also dis/like $food/$music/$actor/$politician", having more billions of people with those knobs at various positions can not really help the boredom.

There is something to this, on many levels. We can hardly look each other and ourselves in the face: https://www.youtube.com/watch?v=S1J6TFHCevg <-- that's just the tip of the ice berg, as we all know. The price of our "functioning" is to not think of these things. But when you think of them, really think of them, I say there is hardly anything as "exciting" as the idea that this is still going on, it doesn't need to, and it shouldn't.

I still firmly believe that we for the most part actually do want to be able to look into the mirror and the eyes of our children and be more than fools telling hysterical lies, in hiding for fear of someone calling them out. Just look at the mental gymnastics of people either rationalizing their complacency as being actually the decent thing to do, or as them having no choice. It's not because they want to defend their being "bad", it's because they really don't want to be bad, and even just getting up in the morning and living the day as themselves is a struggle/achievement for some.
But you know, both many great scientists and philosophers and psychologists and so on, sometimes just "authors", have written and talked about alienation for decades if not centuries. Sure, hindsight is 20/20, but what is even worse is the people who think a fat salary and the fact that they are alive, while those greats are dead, somehow means they don't have to understand any of it. Calling them "technologists" is just about right. To what I would call thinkers and scientists they're like someone who realizes they can catch rain in a barrel instead of just holding their head back and mouth open, to drink at will -- and shows up in a Poseidon costume the next day. That's how little they know about how little they know. End rant :)
