Progress in a purely capitalistic sense, maybe—but in terms of human knowledge and innovation in technology, absolutely not.

Besides, in the same way that being an engineer with no people skills isn’t a desirable thing, there are plenty of problems with knowing one’s business domain only at the surface-level:

1. It’s always these types of people who end up pushing for unrealistic, and many times, senseless engineering goals from management positions so that they waste a lot of the company’s time and money just by existing in it.

2. It’s these types of people who prioritize profits at all costs, even if it could endanger a customer’s life or data security.

3. These types of people are very easily replaceable, because people are by default not inclined to learn about the world around them, and hence they’re dime a dozen.
