Some people legitimately think the purpose of life is productivity. I see quite a few on twitter and I can't help but stare and study them like some alien lifeform.
You might be using the word "purpose" in different senses. The one you're responding to likely means that "the selection bias inherent in our perspective on the world selects for traits that enhance reproduction".
For sure. I'd legitimately love to get inside their heads and see what makes them tick because it's a completely foreign mindset for me.
I saw some recently on twitter who were discussing how they run their relationships like a corporate business... They have standups, 1on1's, scheduled relationship sync up meetings, etc. As if doing this bullshit during their day jobs wasn't enough.
I've played a game called Prosperous universe and witnessed the end of capitalism. Think about it. A game where the enjoyment is derived from economic activity and it's growth. At some point you reach the end of the tech tree. There are no new frontiers to discover. There is no need for further productivity. The game is prone to making itself redundant. If there was no base limit and bots were accepted the entire game could be played by a single player thereby eliminating the need for all other players.
When you consider this inherent contradiction you really start wondering what the point of capitalism is. You reach the end and stop playing. Why haven't we stopped "playing" the same way I stopped playing?
There is an existential crisis at the core of capitalism. Productivity can only exist for the sake of leisure.
