Do you play the Piano? I'm self-taught, learned while working nights at a hotel on the lobby piano.. 
I wish I could play the piano, it is so beautiful! Has it been around for long?
They were invented in Italy in1700 so in the big picture no. No better time to learn then now. 
That seems like a long time haha, but I guess not in the span of all things. Is it hard to learn
The earth is 4.5 billion years old so it's not that old.  The word "piano" is a shortened form of "pianoforte" so it still hold's some of it's original flavor. 
Who came up with the piano
Piano
The piano is an acoustic, stringed musical instrument invented in Italy by Bartolomeo Cristofori around the year 1700 (the exact year is uncertain), in which the strings are struck by hammers. It is played using a keyboard, which is a row of keys (small levers) that the performer presses down or strikes with the fingers and thumbs of both hands to cause the hammers to strike the strings. 
The word piano is a shortened form of "pianoforte", the Italian term for the early 1700s versions

“You want to play some jazz at my home?” I said sure. So we got my drum-set to his place. We rehearsed a couple nights a week – drums and piano. These sessions were my lessons with Sal. Then came Ben Johnston. I knocked at his studio door. I went in. There was silence everywhere. He was in his rocking chair, staring out the window. I showed Ben the score I was working on. I played through it on his piano
