Agreed.

La Bruyère in 1690 wrote a very famous phrase "Tout est dit, et l'on vient trop tard depuis plus de sept mille ans qu'il y a des hommes et qui pensent." (Everything has been said, and we're too late after 7000 years of human existence and thought.)

I can't find the quote right now but Aristotle complained once that the level of comfort attained in his era and city was so high nobody would ever conceivably want more.

It's fairly obvious that the breadth of human ingenuity is infinite and that there are orders of magnitude more inventions to make than have been made.

Not all inventions are useful; one could argue humanity would be much better without television, Facebook or nuclear bombs for example. But one just needs to look around to see how our world is inadequate and broken.

Take transportation: today we use huge metal cages (cars) or metal tubes (planes) to move a bunch of ape-like creatures from one place to another, at great expense and risk. Why can't we fly? We say we fly when we're in a plane, but we don't; we are flown. I want wings (or something) that let me take off and land using my body's energy, just like a bird.

I don't know if individual flying can be achieved using genetic engineering or by building a contraption that one can operate with his arms or legs, etc., but I do know that cars / planes / boats / etc. are a ridiculous and laughably overkill solution to the problem of personal transportation.

Human-powered flight does exist, it's just not very good because people are weak and heavy. https://en.wikipedia.org/wiki/Human-powered_aircraft
Well, leaving aside the problem of taking off (which today is improving thanks to electric motors), I guess one could say that gliders[1] are the closest we can have to human-powered flight and it's highly efficient in terms of energy consumption

It's "not very good" not because people are this or that, but because... it isn't very good yet: which means it needs to get better.

That's exactly what inventing is about: making (existing) things better, until they're so much better, they become a different thing altogether.

> It's "not very good" not because people are this or that...

Denying reality is for daydreaming; it will not get anything invented. Sufficiently advanced technology may be indistinguishable from magic, but it isn't actually magic.

You should try a bicycle.

If you want actual wings, that's just one of those problems that need absurd amounts of money and brains to figure out. Genetic engineering is certainly a lot more difficult than inventing Nitrocellulose.

I'm aware of the existence of bicycles. They are not as useful -- or fun -- as the ability to fly would be.

I don't understand your point at all. When something sounds far-fetched / difficult / expensive it means it's actually more interesting rather than less.

My point is that this thread started with the assertion that all easy inventions are already gone and it takes a lot of effort to invent something novel. You countered with flying via genetic engineering, which to me doesn't sound like something reasonably simple that hasn't been invented yet.
Oh, ok. I was concurring with the comment that said "There are plenty of inventions yet to make" and not really voicing an opinion about their difficulty.

However, after rereading it, I disagree with the top comment that said that "Centuries ago, it was easier to think of things to invent".

It's never easy to think of something to invent. Finding the problem, even just thinking there might be a problem where noone sees any, is a big part of any invention.

Also, in the past, inventions required a much larger leap of thinking than today. When we speak today about growing wings on creatures born without it, we kind of accept the idea, because we know it's already possible to grow eyes on flies' legs for example.

But inventing the steam engine, or disproving "spontaneous generation" and inventing vaccines, sound to me much more impressive because those people went where no one had dared go before them.

But the thread's based on an invalid assumption. I posit that inventions were never "easy." They just seem that way in retrospect, from the outside.
Easy is relative. So is "invention". I invent things most days of my life, but they aren't that novel.

People are crazy inventive and always have been. But today, it is far easier than it ever was before to learn about the best inventions others already figured out instead of reinventing the wheel.

Bravo for attitude but we should not forget energy conservation rules.
