Everyone would be wandering around in long robes; camels would be the normal form of transport. Hospitals would be monasteries or nunneries and you’d get prayed for. The inventors of anything after 1602 would have all been burned at the stake. Slavery would be a thriving trade. There would have been genocide of every race south and north of the US and the death penalty for everything would be in force. In fact, it would not be so different from Afghanistan.
Oh, yes, and you'd be British.
