hush, he needs a new bike. Don't be so negative.
It's possible that new tires would make the bike feel less sluggish on the road. But 47mm tires are pretty big, they might feel sluggish even if they aren't really slowing you down much. They are going to be more secure on rocky paths, so that is a trade-off you have to make. I ride 38mm Gravel King SK, and they don't feel sluggish to me on the road. YMMV
