I think that if, when you die, everything in the universe becomes frozen in time (from your perspective, natch) there might be a valid argument there, @Sexagesimalian.
Tahani decided on an arbitrary length of list and then moved on to do new things. How long will there be new things? As long as there is time. Human scientific advancement is moving at such a pace that there is no way one person will ever manage to keep up to the date with everything. Even if you decided to devote your life to, let’s say, only Quantum Mechanics, by the time you are up-to-the-moment with your understanding, you will be way behind on Thermodynamics or Gravitation or Superstring or whatever… and so you study that until you are up-to-the-moment, and by then you are again out of date with Quantum Mechanics!
Love reading? I assure you that until the heat death of the universe (or mankind’s self-annihilation) there will always be more to read than you have time to read. Always. And if there are people who love writing as much as I do, then there will be new books there too! I could spend several eternities just waiting for Sir Pratchett to finish more books, and read those, and then read the next Scalzi, and then the backlog of Le Guinn… and by the time I finished half of that there will be new, better sci-fi authors out and I can read all the classics again with new appreciation!
Could I do that forever? I mean, nothing ever lasts forever. There is no “infinite” when it comes to time, since it is linked to space and eventually all of this will end in the heat death of the universe, but let’s assume The Good Place is a place? We’re talking tens of thousands of years at least. Hundreds, possibly. And at no point having to worry about food, or sickness…
But now I have to worry about loneliness? What if all my friends up and leave? I’m not ready to go, but now I have to forge new friendships with people I have no existing connection to? Gah. Suddenly I’m in the Bad Place.
I would still argue that Eleanor was abandoned. Yes, Chidi “held on” for a while (hundreds of years? Dozens? Thousands? Some period), but he still decided that leaving Eleanor was a moral choice. He put his needs before those of the woman he loved, and hey, I am all about that sometimes. You can’t be totally selfless without losing all sense of self. But in the literal Good Place, you’d think that one of the infinite number of tweaks would be the ability to choose when you want to go, and not suddenly decide “it’s time” and then, poof, gone.
I want to stress again that I’m an atheist. This life, this one, fragile, stupid, terrible life is all I think any of us get, and so thinking about a concept of eternal glory is a nice hypothetical (like, say, discussing if Aragorn could beat Boromir in a sword fight, or if Gandalf could beat up Anakin Skywalker). But it’s flawed at its core, in my opinion, if the best of all possible dimensions ends with a woman terrified of being left alone by everyone who matters to her, who have found meaning through her connection to others, is then abandoned for years (hundreds of years, thousands of years, months, any period of time).
That’s profoundly depressing.
