ELI5: What is 'Optimistic Nihilism'?
gpt
Basically and without boring details?

Accepting that your life and existence has no defined meaning/purpose at all.

And at the same time accepting that this absence of meaning/purpose is for you to fill up with your own decisions, things that you believe in and want to be. May it be a dream, or a hope.

The Universe is gonna fade into darkness someday according to the laws of thermodynamics, but why would you bother if you'll be long dead before it? Go outside and watch all the stars, you were born in a time they had never burned so bright.

Accept all the painful truths Science can give to you, and make use of it not to "Get sad because life is meaningless", but instead feel happiness for knowing you're free from Dogmas.
