At some point, sure. Programmers will all be out of work once computers can effectively program themselves. But right now, it's not so straightforward. The OP describes call centers, and that's a really good example - while a simulator can present call center tasks to a job candidate (with simulated customer voices, for example), a simulator responding to customer service calls would not be nearly so successful.

A video game simulation is a controlled environment (HR can create a set of scenarios to be tested in the simulation) but real life is more random. It's up to HR to create a reasonable sample of work scenarios for the simulation, and the quality of those scenarios is directly proportional to the quality of the information you get out of the simulation. And it's also important to realize that they not claiming that simulations are the only hiring tool you'll ever need. They're just better than interviews alone (and way better than unstructured interviews, which are almost worthless).

I will say that I don't know a single organization that uses a simulation and NOTHING else. It would be very difficult to assess characteristics like interpersonal skills and job experience. A simulation is usually just one step of a larger hurdle-based system (usually a late step, since they tend to be expensive per-applicant).

Life expectancy has been going up at a pretty consistent rate in the United States since 1968.

For either medicine or sanitation to have made a substantial effect on life expectancy, we'd expect the timeline of advances in each to mirror advances in life expectancy (e.g. major medical breakthrough in 1973 matching a substantial increase in life expectancy in 1980). That clearly doesn't happen. Sanitation and medicine are both only a small piece of a much larger puzzle.

You clearly don't have or know anyone with an actual mental disorder. There is certainly harm done by false diagnosis/labeling, and some people certainly milk their diagnoses, but the majority of people with mental disorders find it somewhat of a relief when they discover that they have a condition that 1) is not their fault and 2) has treatment options.

Think of it this way - if you grew up, and throughout your elementary and even high school experience, you had skills and abilities that other people thought were bizarre, people always looked at you weird and you didn't know why, you had uncontrollable tics that other people just didn't, you were frustrated daily because you had a very difficult time controlling your own behaviors, and you constantly got in trouble because these behaviors were judged to be "bad."

Finding out "other people have this problem too, and here's what you can try to alleviate the symptoms" is important to help these people become "normal, productive members of society." Your assertion that diagnosis will "lead the majority of them to make excuses" is completely unfounded.
