I think what you're saying here supports my original doubt that people will come together as a community to create things. The entertainment industry has a profit motive for keeping people using their entertainment. If people stop wanting negative content, then the entertainment industry will adapt (or the content already that way will become more successful to the same effect). The profit motive, as you describe it, only makes it less likely that we will move away from spending our time online in the future as profit incentives push online entertainment to become more addictive/appealing/exciting/pleasurable or whatever keeps people coming back.

At the end of the day, my worry is that your worldview (as I understand it from our few messages, please correct me if I get something wrong) is not compatible with a future where technology stops progressing. If technology keeps progressing there will be a point where AI can be a better "human" companion than a human (e.g. be like a human perfectly optimized to be your friend). When this point is reached, the idea of a community starts to break down it seems to me. The day will also come when our understanding of the brain is so good that we can cut out the middle man of our senses and stimulate our pleasure centers directly without long-term health effects. Considering that all "good feelings" are combinations of brain chemicals and neural circuits it follows that stimulating the pleasure centers directly is the best way to maximize "good feelings".
