Are humans centuries old in technology ??

We humans consider ourselves as the most superior living beings on earth and we always take pride in it, no matter how lacking we are in many things? Are we humans centuries old in technology ?

Right from latest curvy smartphones to latest operating systems, high-end gaming consoles to big bang theory, Einstein to Stephen Hawking, there is only progression  and no decline in advancement. Today when you are reading this, by this time there would have been so many product launches right from 1 TB RAM and unlimited to babies born from printers :)

What if ? 
It has taken so many centuries to discover, invent and formulate the present day we are living - locomotives, mobile technologies, internet, web tools, softwares,  applications, ideas based on these kinds of technological advancements and many more but are we really advanced in technology ?

I guess it was really 1 1/2 years back I was watching this particular program : Curiosity - Is time travel possible by Stephen Hawking, after watching this program I

was really astonished to know the fact that time travel is possible but the proposed idea was that, to travel time is not possible with the technology available with us. To make it possible, technologies that are more advanced than us which is not possible in real time, is very necessary.

In the same way, there was a scene in a movie which states that the most greatest ever invention made was Big Bang Theory. 

Likewise there are so many things which cannot be understood by the human minds. If it cannot be understood by the human minds - which we consider one of the greatest inventions, lacking behind centuries when compared to the unknown aliens.

If aliens (just like the term foreigner), exist, are they really more advanced than us or do they lack in technological advancements? or they waiting for the right
time to hit the earth when we are in technologically advanced ?

To be continued....
