Alright commies, I need you to enlighten me sbout some stuff. Like I am truthfully trying to understand this here

Crowd sourcing both products and scientific studies is a thing already and works fine.

Socialism is moneyless so no, no one needs to get paid.

oops i meant crowd funding. Crowd sourcing would just apply to certain things

There's been success with crowdsourcing scientific research hasn't there? [email protected]/* */ etc?

There would be no debt that can not be paid back because the lack of charging interest. Of course that isn't the only way around that either.

what is M-C-M'?

You can't do that now. Your pay isn't the fruit of your labor. It's the compensation you get for selling your labor. The fruit is going directly to the company you work for.

I'm sure people will still want to upgrade their electronics so there would probably be outdated computers for you to tinker with. Either they would be gifted to you or maybe you have something to trade or a service to offer.
Would probably get recycled.
No. Socialists make a distinction between private and personal property. Your clothes are personal property.

Before I start, there's a clarification that needs to be made.
Socialism is the collective ownership and democratic control of production and distribution (which is effectively the worker's ownership of the MoP).

There's two ways about it, and that's decentralized and centralized planning. Decentralized planning is what you're thinking of and would come after generations of people were living in a socialist society and it would be brought about only after the destruction of liberal ideology.
A centrally planned economy requires a state and is what we would (more than likely) see in our lifetimes.
In a decentralized economy, it'd be local councils that get community input (from my understanding at least) to acquire resources from other councils.
In a centralized economy, it'd be a chain of command, so (for example) it'd go local councils (lc), county councils (cc), territory councils (tc), region councils (rc), country councils (coc), inter-country (or global) councils (icc), so ic->cc->tc->rc->coc->icc with varying communications at each level (and yes, this will be much easier with computers being able to do all the calculations).

As necessary. If a new factory needs to be built, then it'll go through a process to get approval for being built (including resource allocation and a timeframe).

Same way it has in the past, just without the incentive to create more profit.
"What's the incentive then?" I hear you ask.
Simple: If I make a robot 2x more efficient then I can get 2x the amount of time off, and this would go down the line of improving other robots so that others could get 2x the amount of time off.

Whichever level of councils would need to communicate about it.

Besides still believing that money (as we see it currently) would exist under socialism/communism, no not really.

(sorry if some points are unclear/confusing/whatever, tired)
