You haven't seen all of them, but the more you see the less value you get from seeing another. So we can conclude that living for an eternity wouldn't be particularly more interesting than living for 100 years, as 100 years is more than enough to see many things in each category. You might not become a world expert in everything, but experiencing the things worth experiencing in the categories doesn't take particularly long to do and after that life is just padding.
The main reason to live now is that there are new interesting things coming out still, since computers are still young. That adds new things over the years. But interesting progress isn't really the norm, it isn't like physics or math has gotten any more interesting over my lifetime and I expect computers to get there before I die and then there isn't much left.
Edit: For example, everything we produce today is based on the same math and physics my grandfather learned in college. There has been no practical progress since then there. Main thing since is new tools enabled by computers that are more precise or automate things, that is interesting but the discoveries enabled by more automation/precise tools will run out at some point.
Turn to creating (art, science, a better mousetrap), and there’s no end in sight.

I'd agree that at some point being "creative" feels like just another kind of killing time with minesweeper or crossword puzzles or whatever.
It should be. As you get to see the heat death of the Universe. Or at least experience its beginnings; or at experience an ice-age or something.
But life boring because consumption becomes boring? Nothing could be further from my experience! Instead of a focus on consumption, or even a focus on creation, I find a focus on skill-building to be where it is at. This summer I have taken up beekeeping, keeping chickens, and learning to fish. (We also got a second puppy which is also an adventure in getting to know this dog's way-of-being and how we can train her to be one of us even as she changes us by her inclusion.) Even though I've put hours and hours into all of my projects I am a novice and I recognize that. I have more questions and ambitions now than when I began. With fishing I've caught 9 different species so far this summer. Now I want to catch another set (pike, walleye, perch, catfish), try new lures and learn how to use them, explore new places to fish, and learn how to clean and cook them. (Catch and release solely so far.) I haven't harvested honey yet from my hives nor dealt with mite infestations. With my chickens I'm still learning their patterns and waiting for the first eggs. The chickens also forced me to upskill my building abilities so I could make them a coop and run.
I also have in my wheelhouse of fun-to-me (ie not work) skills house repair (remodeled a bathroom last year), my own car repairs, woodworking, reading and writing, baking, sourdough, kombucha, beer-making, yogurt making, gardening etc. I am no where near a master in any of them and I don't do them all all the time. There is so much fun in learning a new skill, and seeing over time how I become better at it. I am a master of none of those, but I keep growing in all of them. There's always someone else better than me at an aspect of each of those. There is always a new thing to learn to do, something to be better at, feedback to receive. Any one of these could keep me extremely busy for several years trying to master them.
And there are definitely more skills than anyone could learn in a lifetime. Off the top of my head I have on my to-learn list leatherworking, blacksmithing, circuitry, furniture building, 3dprinting, basic microbiology and chemistry, cnc machining, publishing a book, photography, guitar, piano, singing, hunting, target shooting, skeet shooting, and on and on. This is my list, I'm sure other people have their own list with really cool things I've never thought of. (And once I do they get added to my list!)
I think the difference is the mindset. It isn't about whether or not someone else cares about the end product. It isn't even about whether the end product is really any good. It is about me being able to do it adequately. It is about growth and change in myself. If I judged myself by Hollywood, YouTube, or Instagram portrayals of any of my hobbies I would despair. I'm not as good a fisherman as Richard Gene. I'm nowhere near as capable with hand tools as Paul Sellers. My sourdough is pathetic compared to Maurizio of The Perfect Loaf. I don't have the teaching/communication skills of someone like Feynman. But that isn't the point. The point is I'm better at something today than I was yesterday. The point is I did something successfully, even if it isn't perfect. After enjoying that success I can always find more areas to improve which is a new challenge to accept.
Boring? Only if I gave up my personal drive to improve and find things to do.
edit: I focused entirely on skill here. There are also interpersonal relationships that take time and effort and can be richly rewarding. Even without all of the above my life would never be boring because of the people in it.
So at least to me there aren't many things left worth learning. Maybe chemical engineering could be interesting to learn, as it isn't entirely clear to me how people work with chemistry, I have no idea what I'd be able to do with a few years learning chemical engineering.
