Earlier quoted context omitted.
A good strategy as an analyst is to predict a downturn coming. You can be wrong for six or seven years, and then if/when there is a downturn you say, "I told you so!"
The thing is though, there are just as many people saying "it's different this time". The person predicting a downturn will inevitably be right. The other person... not so much :).
There is a huge difference between this time and last time. The internet is much more mature for one. People depend on web apps now in a way that's not going to change just because the market swings.
Another thing that's different is that people spend more time on software distractions when the economy tanks, not less, so a global downturn is likely to drive consumer spending away from the real world into the virtual.
