Yes, and that is exactly what we see, as the article you linked to indicates ...

The cosmic star formation rate is seen to peak about a redshift of 3, about 11,500,000,000 years ago, when the universe was about 2,200,000,000 years old. It has fallen off by about a factor of 10 since then. See, for instance,
Hopkins & Beacom, 2006.
