You’d want to also consider, that desktop components were not created for 24/7 usage. My previous motherboard died by overheating south bridge – it likely wouldn’t happen in a desktop usage, but 24/7 didn’t let it cool ever. The chip has a small ‘volcano’ in the middle now.
But we already have countries with free healthcare and education for citizens.
UBI experiments are also ongoing in many places and government programs are usually available at least for limited groups like disabled people, veterans, some unemployed, etc.
And less consumption-centric world would do much more good for these initiatives than further automation of low-level jobs, I think.
This should be handled by (auto)mod tools, allowing good faith users to help filter non-fitting or low quality posts, and preventing bad actors from downvote fireworks.
There are possibilities to limit available downvotes either by throttling amount per time/community/instance/user, by demanding to have a certain “reputation” in the community/instance or by making downvote cost your own “reputation”.
None of the above is perfect, but IMO outright removing a right to disagree is against community interests.
Currently I can either leave a “harassment” comment: “wtf this is doing in this community”, make complain to a mod (if there is any active), or ignore the post. Neither help community grow stronger, I think.
