I think the great thing about Satisfactory is you don’t have to “beat it”. Just do what you want in it, proceed as far along the tech tree as you please, and if you happen to get all the way through it, congrats.
I’ve played almost 1000 hours and haven’t beaten the last Space Elevator tier. But I’m not bothered by it. I like so many of the other aspects of the game that I don’t need to “beat” it. I like making every production line 100% efficient, I like building beautiful buildings, and I think the game is so much fun to simply run around in. It’s honestly the game I’ve had the most fun moving around in since Titanfall. Titanfall definitely edges Satisfactory out in this department, comfortably, but Satisfactory is still a blast to simply explore the world in.
That’s just my take on it though. Your opinion of it is definitely valid. It is a big grind to get all the way through the last Space Elevator tier.
