"I can't imagine the displays being used are very high quality" ??? if they provide the amount of savings outlined I doubt spending extra 200K on quality screens will be an issue
Although that's probably regulatory stuff. Most governments don't let arbitrary airtcaft do aerial topography-grade stuff, and companies err on the side of caution.
The economics literature begs to differ, though it's not a 1:1, as the improvements are usually specific to an area of the market while the labor market is much less specific, which actually means that the benefits are less because they're dispersed over a wider group of people, marginally improving the lives of people who didn't even have productivity improvements in the work they do.
