  I'm not sure that we're in a "bubble" in the 1999 sense 
  that people worry about, 

I think the scale may be different but we definitely are in an artificially stimulated economy. The effects will only be seen post Fed's interest rate hike. And the way they are shying away from doing so makes me feel that the market is not ready to stomach that.

The access to cheap money has brought in a lot of players into the market who otherwise would have been sidelined. I think it's not only evident in the startup/unicorn sector but quite so in the building/construction sector as well. I see all around me skyscrapers & apartment complexes being built in an unprecedented rate and people buying half a million dollar+ houses where quarter of a million was too high (as you can see I'm not in Cal).
