Not at all depending on the timeframe you want to talk about in.

For example, one way to travel around the galaxy is to find some other object with a very fast orbit and colonize it. Then as it goes along you throw off seed ships. This is the whole idea behind 'von neumann probes'. Massive numbers of things working in parallel can get a lot of work done.

I understood the article above saying we could finishing colonizing most of the galaxy in little time, say 1000 years. But the galaxy is much larger than 1000 light years so without FTL travel (impossible afawk), that's why I said you can't do it.

But were you saying "get started on this in 1000 years" instead of finish in 1000 years?
