Indeed our knowledge has advanced. I wonder what folks a century ago would think of our abilities today in technology. There seems to be no end. Exciting yes as long as it is used for the good of mankind and not the destruction. With all we can do we could become our own Gods. I think of Billy Joel's Song Two Thousand years. Take a listen if you have not heard of it. It imagines the next 2000 years in the last verse. Thanks..

There will be miracles
After the last war is won
Science and poetry rule in the new world to come
Prophets and angels
Gave us the power to see
What an amazing future there will be

And in the evening
After the fire and the light
One thing is certain: Nothing can hold back the night
Time is relentless
And as the past disappears
We're on the verge of all things new
We are two thousand years
