You guys should stop buying Bitcoin - how am I going to fatten my wallet if the price keeps rocketing up?
What are we going to do when the Satoshi achieves parity with the dollar?

You're right, honestly. I was a huge skeptic of BTC for a long time but am slowly realizing just how influential it may be. I have this odd feeling that in 10-20 years owning even .1 BTC will be incredibly valuable.
The way I see it:
If there are major wars, BTC will go up
If there are problems with countries currency, BTC will go up
More investing firms are adopting Bitcoin (finally)
There is a finite amount of the currency
Internationalism is growing, which is reducing powers of national governments. That should also reduce their power to control national currencies. So btc and other neutral international solutions will grow.
