There is perhaps a bit of confirmation bias in this view, but I see people usually erring in the other direction. E.g. there's no such thing as "too fast Internet" today, people find new ways to suck up all available bandwidth.
And the worst offenders of this narrow-mindset are, wait for it, no less but the trained scientists themselves (not all, but the ones who didn't have exposure to engineering thought).
When we (engineers) say: "If you build it, they will come", what we really mean is this:
- If you build it, and they come, great.
- If you build it, and they don't come, too bad. Let's try something else.
- No one predicts the future like an oracle, but we'll try our best to make our claims come to fruition.
Our audience (the investors) knows that. We (engineers) are not out there for the truth. We're out there to try things out based on an educated guess, give it our best shot, and see what happens.
That's how the real world works.
You can easily look back at things people have built and people have come to (computers, planes, cars, etc)... But there are far more things people built that no one came for, and which we don't even know of because no one wanted them.
Solar roadways is an example of something that was an infrastructure project that was built out in a few places, and by all accounts was a failure.
The concorde seemed like an obvious "build it, people will want it", but in reality people didn't come for it, so it was retired.
And there's countless other examples, from 3d movie theatres, to dotcom ideas to all the things we don't know of.
