Ok, maybe not necessarily world changing, but who knows :)
I'd love to hear your idea of anything that you're excited if exists but personally yet have not time / money / inspiration / whatever -> to create!

Examples:
An app that does X
An object that does X
A new art form that is X
A new concept which is X

Here are some more clear and pretty recent examples:
Uber
Educuring (the creator is Simbi star Briana Miller)
Couchsurfing
HelpX
Polyamory
Digital Nomadism
Simbi
Basic Income
AI
Art Therapy
Robot Farms
Community Housing
Permaculture
etc etc etc.

Very important! This is only for open minded people. For people who don't care if someone "steals" the idea. For those who believe that existence and implementation of potentially world changing idea is way more important than ownership / rights / monetization.

For Simbi people.

Why am I requesting this? Because the list of such ideas will finally appear and people will start looking into it, becoming inspired and ... will just start working! By contacting the author and collaborating or just by implementing on their own. Yes, ideas' implementation will compete, in a healthy and mutually beneficial way. Or rather - beneficial to users, to the world.

So the plan is to create public spreadsheet, maybe website later, where people will observe ideas, maybe vote and, most importantly, join, collaborate and implement.

Please start sending me your ideas, in any form. I will classify / categorize and create most likely Google Form that will publish to Google Spreadsheet.
Also, as always I pay you my symbolic and symbiotic 1 simbi :)

Thank you and love you, my Simbi family!
