Are we close to the dot agile crash?

One of the best articles I have recently read - "Agile Ruined My Life". The situation, from my point, is very like described and greatly reminds to me our position before the dot com crash - the idea by itself is very good, but we were trying to make it work too fast without properly thinking, using wrong tools and with a lot of people who factually lied consuming the idea, not developing that.
