| Malls as coworking space would be literally the arcologies of dystopian cyberpunk. No windows, no natural light, never going outside in the real, natural world. Just one giant homogenised hermetically sealed world. It wouldn't be "best" for many people. Maybe "convenient" for bosses who don't like how much productivity they lose when a Meat Flavoured Productivity Unit has to go get a haircut or imbibe sustenance.... |
For example: I used to work at GoogleX's "San Antonio station", which was a converted shopping mall, and it had great lighting, even on lower floors.
With multiple employers in same building, you'd also have many more socializing options -- including random colleagues who drop by to run errands.
Besides, what would you suggest instead -- let them turn into suburban blight?!
