Earlier quoted context omitted.
> companies are chasing profits at any cost What does that mean? This was addressed in the article. Critical services are on the internet because remote workers need access to them. I don't see how profits factor into it.
Those remote workers wouldn’t have to be ‘remote’ if there were other workers hired on site.
A remote operator can manage dozens of such sites, a single "local" person might be close to one point, but the next control point is going to be miles away, so you either need much, much more people to station one at every valve, or have a situation where flipping a switch in all the "sites" is very slow because requires the "local" person to drive many miles visiting each location.
No, there's a reasonable objective need for this management to be actually remote - there's a discussion on how this should be implemented in a secure way, but it does have to be remote.
