This just makes me think that Alberto Santos-Dumont also "invented" heavier-than-air flight, only 3 years later and it was better.
Wouldn't we still have the same flying ability if the Wrights never pursued flying?

The wind tunnel work was crucial to their success, arguably the single most important element. It enabled them to iterate their designs and compare them quickly. In today's language, it helped them to fail fast.
Had they been better funded, they might have committed the error of trying to iterate mostly with full-sized fliers, which would have drastically slowed down iteration.

#5The real key is advancement in metallurgy and engine technology made a lightweight engine feasible. The correct formula might have taken a couple years off the time frame, but no more.
As always you see farther than others by standing on the shoulders of giants.

Yes, it enabled them to not only fail fast, but to fail and live to tell the tale! Much talent and knowledge was lost in the people that died trying to fly before them.
It's also amazing to read about the many pilots who died trying to cross the Atlantic before Charles Lindbergh did it. The journey nearly cost him his life as well, and it took some time before such flights were safe enough to routinely attempt.
Early aviators had some serious guts.

I can't think of any technological advance that was achieved primarily through the effort of a single individual - in retrospect, it seems "obvious" that the fundamental principles had been in place and that it "only" took someone to come along and put them together in a new way.
I'm a firearms enthusiast and have spent some time studying the development of small arms. If transported back to the late 18th Century, I could explain and document the mechanism for an automatic rifle suitable for use by infantry like an AR or AK - but I likely could not produce one, and certainly could not produce them on an industrial scale. The metallurgy simply wasn't up to the task, nor was the machinery of the day. The metallic cartridge would't even make a lot of sense; as the percussion cap hadn't yet been invented. Even a manually-operated mounted Gatling gun wouldn't be possible without it.
Once a stable, impact-sensitive explosive suitable for use as a primer was invented, everything was in place for the invention of the metallic cartridge - and that's exactly what happened. Metallic cartridges lead to breech-loading firearms, which lead to the bolt action, which in turn lead to automatic and then semi-automatic actions. Neither of the last two made much sense until the invention and adoption of smokeless powder, as traditional gunpowder leaves so much residue that it would only work for a few shots before "fouling".
All that said, there are individuals that push the state of the art forward a great deal through their contributions. John Moses Browning, for instance. He created the first gas-operated machinegun and several of his designs remain in use (essentially unchanged) by major militaries around the world more than a century later.

#8This was really interesting. I've always viewed the Wrights as "hobbyists" or "tinkerers" - but now I'm going to have to do some research on their lives. If the impression I got from that article is remotely accurate, they were engineers. It seems almost insulting to call them "bicycle makers".

I'm guessing it's a marketing pitch from the era. The "bicycle makers" narrative sells better than "two smart guys did something smart."

Check out the book The Wright Brothers by David McCullough[1]. You will see that they are anything but tinkerers, but more the founders of aeronautical engineering.
