The truth is the opposite: https://news.ycombinator.com/item?id=12433966
Wrights were actually very secretive and they were reluctant to publish anything before they got the patent. They were so adamant about the patent that they didn't do any public demonstration of flight for years until they were literally forced by competing claims. In those times people making claims for "heavier than air" flights were numerous and it was hard to take anyone seriously unless they do demonstration. They not only chose not to do so until they got patent but also did almost nothing to enhance their technology meanwhile. Their contribution except for first flight is very marginal and their rest of the lives are dominated by nothing but patent worries, bringing massive lawsuits on others and getting royalties. They also made a very generic patent claim essentially asserting that any system that produces lift is covered by it. This produced a lot of friction in bringing new innovations to market leaving USA significantly behind of Europe.
In addition to this, there were flight enthusiasts all over the world, and particularly in France. They were hang-glider enthusiasts at the time, as that was the cutting-edge flight technology. One of the famous hang-glider pilots died due to his belief that a hang-glider ought to be controlled by shifting one's body weight, which led to a fatal stall. This further convinced the Wright brothers that "the control problem" was the most important problem to focus on.
A lot of people wanted to fly.
This is all tangential to your point, though, and wasn't meant to take anything away from it.
"Some day there will be, say, six great wireless telephone stations in a world system connecting all the inhabitants on this earth to one another, not only by voice, but by sight. It's surely coming."
Take connecting the entire world. Even after the technology existed and had been deployed (the very early system that gave rise to the internet as we know it), people didn't look at that early version connecting a handful of places and think, "Wow, this could connect EVERYONE!" They didn't stand there, looking at the terminals of two connected computers, and imagine a connected world like the one we live in today. They didn't talk about ecommerce and social media global events being reported on in near real time. No one had to roll their eyes, because no one was making these grand claims.
I can't find the link now, but I read somewhere that it took YEARS after the Wright brothers had achieved first flight to get the attention of the world. People didn't see how transformative that thing could become, yet the proof of concept was there.
When you look at all the big tech moments in (recent-ish) history, the car, modern computation, the PC, aviation, you don't see people coming out with these grand declarations before the fact. And it's not for lack of intelligent, visionary people.
So it makes me wonder, whenever a person makes such grandiose plans, and they're not fiction writers, what's so different about them that they'd be able to see so far ahead?
Maybe they're different. How would I know? But history makes me skeptical.
