I think in terms of the money supply, assets haven't gone up in excess of the increase in money. so not a bubble yet. too many people skeptical of it to be a bubble.

I don't see any big progress or innovations to get velocity into money so we are going to be stagnant for some time.

give it 10-20 years then baby boomers won't be around and we can proceed with a global project against climate change and for renewables, I think that will be it.
