The reality is that it depends on the person, because autism spectrum people have various intensities of various traits that might make them practically useless in even the most trivial job, or a strict adherent of the systems to a problematic degree, or somewhere in the middle but incapable of working with others in a way that's really difficult to manage, or they're just luckily well-suited for the context. Doing well in that sort of environment is a skill or disposition that's well-suited to a low degree of volatility and a high degree of predictable behavior, both of which are not so likely to be present in someone with autism. Seeing how people who become managers in tech fail to adapt to someone who works in a marginally different way than they'd like, I don't have so much optimism unless their superiors have specific training and possible accomodations. Some autistic people are no-doubt brilliant and super productive, some can't do anything on their own, much like the general population I suppose, but I'd wager with a lower chance of being productive in a very typical office setting, even if they're brilliant.
