Errrr, there have been plenty of advancements in space exploration, just a few years ago we didn't even know that other stars had planets, now we're aware of hundreds of them. Just last year it was discovered that the physics of the universe is different in different locations.

Flying cars? The reason we don't have those is because they're not practical, and incredibly dangerous.

As for technological advancement, we have the Internet; not to long ago we started having the Internet on our phones, and it is more widely integrated into our society than any Science Fiction movie thought it would be. The Internet is practical.

I think the Internet did more for the world than a flying car would.

The same way like automation replaced jobs of humans and raised the unemployment rate.

Teleportation.

No offence but humanity has advanced more in the last 100-200 years then they did over thousands in the past. I mean why is it humans were fighting with bows and arrows for so many hundreds of years? Why is it took so long for gun powder to be invented? I mean the technological advancements have been astounding since the automobile. We have phones, internet , cars, computers, planes all invented in the last few hundred years.

Man has landed on the moon linked almost every citizen together with a global network of phones, radio's and computers. Go back 200 years and tell them everything you are doing today. You will confuse the hell out of them, we are so much more advanced its not even funny. Then go back to the Roman Empire and try to explain what we have done. Then try the stone age.

Man kind has advanced at such a rapid rate lately their is real no argument that we aren't advancing healthily.

AFAIK, we already did that. They planets similar to earth, with an Atmosphere, regulated temperatures and even oxygen and water. Sadly, they're lightyears away, so there's no way we can reach them...yet.

Apparnetly now they're close to having computers that mimic the human brain. It's possible to concieve the human brain being transferred from a human to a machine, thus making a person immortal. I'm not sure if that would still be considered humans being replaced by robots. 

Weren't these planets too big (and therefore with too strong a gravity) for humans? Also, are you sure they had significan amounts of oxygen? Because as far as I know, I think the only way that could happen is if there was life to synthesise it.

Anyway, if they havn't been discovered yet, that would definitely be the next thing we'll discover I think. It's a matter of a few years.

And yeah, we can't reach them, nor we will be able to in the next few centuries IMO.

thats always gonna happen with any kind of technology

but that isn't making humans obsolete but creating new ways to employ people

like with automation the production got a speedy so humans can do other kinds of work and faster

new jobs of new kind will keep creating

they have computer mimicking human brain to find medical solutions

they don't have a computer which can act like a human brain

about your  immotal comment?it will never happen as robots are not sentient beings so they will not be able to feel or perceive the reality.
