Yes, the article is quite conservative, but on the upside, you can clearly tell he's talking not only to the people listening to his speech today, but also directly to readers who may be revisiting this speech in 2032.

As you know, we seem to have a fascination with reading long ago predictions of the "future" that is now today... and we really like to laugh at them.

I believe his tone is one of "I know you're reading this in 2032, so I'm going to try my best not to be silly."
