These commandments that I give you today are to be on your hearts.  Impress them on your children. Talk about them when you sit at home and when you walk along the road, when you lie down and when you get up.
(Deuteronomy 6:6-7)

The commandments were not just for Moses and the people of his day.  They were meant for all time, for all people.  They apply today, just as they did centuries past.  It seems to me that I don't hear enough about the commandments and their applications today, which means that we aren't doing our job of talking about them and teaching them to those who may not be familiar with them.  Take the time to reread them occasionally and think of ways that the commandments are misused, misinterpreted, and ignored and put them back into the forefront of your mindset.
