The whole article is fine, but Lampson says something that I can't understand quite well:

The fundamental problem with persistent objects has turned out to be: If you actually build a system with a lot of long-lived data structures, if you do a few million ‘new’s,’ the question is whether you just have anything useful, or whether you just have a rubble of objects – and the answer is unfortunately, you just have a rubble of objects.

Wot!? Why inserting a few million records in a database does not end up having a few million rubble rows but creating a few million persistent objects do? I bet only Lampson knows!
