> 2. Accurate estimation of development times is impossible (not difficult, actually theoretically impossible). All estimates of development times are wrong, some by more than an order of magnitude.

Personally now-a-days I care more about velocity. If the team can deliver the smallest value added to the system within a week, we are good. The more constant velocity the team has, the more Management trusts you to produce value and get their things done without the need to have massive estimation parties that almost always end up being wrong.

The sad thing is, once the velocity gets bogged up or waving (Org change, contantly changing directions,..) the estimation parties are here to stay and it's quite hard to get back to where the team was.
