No, we have not stopped creating antiques

Traditional antique items may be falling to the wayside, like containers and trading cards, but we are in an age where we are creating new items which will--as the items age--redefine what the world considers to be an "antique." Our current tech will become tomorrow's outdated but still fondly-remembered antiques. And of course, we are still producing things like knick-knacks, toys, and collectibles; even if those items look way different than antiques from our past. We have not stopped creating antiques; we are simply defining new ones.
