The way I see it humans don't realise it yet but we're all working towards creating a HIVE mind, blockchain to store it, AI and Machine learning to process it, internet and IOT to connect it and quantum computers to run it, all these technologies combined will eventually make humans obsolete. Yes it sounds sci-fi but it's like we're this worm and this tech is a cacoon and next stage is the butterfly
I think we've reached as close to as good as it's going to get for humans, and it's up to something else to take our remanence forward, sadly I gave up on humans a long time ago
