I respectfully disagree. Even if you told me that you felt like working at the UN was a waste of time, I’d still tell you that at least you contributed to a historically unique global institution which at least strives to bring people across the world together.
Not a lot of people here work for Meta, which is why you had to lump in "Random SaaS" like that's remotely comparable. I doubt most people here are working on anything harmful, let alone a fraction of what Meta does.
Unless you think Todo list apps cause Ethnic Cleansing.
>Cooperate with their fellow citizens and fix their banking system
That's exactly what Bitcoin was for.
I don't know where you live, but most places it's the banking system which fixes the citizens, not the other way around.
Only way I imagine being able to fix a bank is with a brick through the window. It's why one level up from where I'm at banks are closing their physical locations, keep no cash, and only have people for 1-2 hours in the morning when only the most obedient are awake and not occupied.
Bitcoin was just a waste of talent and resources.
