Economic growth basically means that workers get more productive. Less hours of work means more output. GDP growth is not really possible without making workers more efficient.
It's interesting how in the last years the old luddie arguments got revived. The idea that automation means that there won't be any jobs anymore get's more and more popular.

In principle it is possible for GDP to grow even if productivity per hour stays constant provided the number of hours worked goes up. I've heard that's an important factor to consider when comparing the GDPs of France and the US, so it's not that unlikely it also is when comparing the GDP of a country in year X and that of the same country in year X+10. (But of course such a thing couldn't go on arbitrarily far because there are only so many hours in a day.)
