Sadly, this statement is predominantly false. That's not to say that there aren't interesting ideas being tried out -- there are. It's just that the ways in which Unix is flawed aren't significant enough to warrant switching to a new system. Yeah, the security model of 'sudo' for any permissions at all sucks, but it gets the job done on production systems, and there are (ugly) workarounds to get better security. Yeah, dependency management sucks, but we have VMs to work around versioning issues. There are tons of people proposing solutions to these types of problems in academia, but Unix is entrenched, there's tons of software written for it, and industry is not going to adopt an alternate platform unless it is 10x better than what's out there. Academia is proposing systems that are 10% better, not 10x better, and add complications to the relatively simple process / file model of Unix.
