In a research note analyzing fourth-quarter earnings, senior U.S. economist Ronnie Walker noted that discussions surrounding AI completely overshadowed what was fundamentally a strong quarter, with core corporate revenues (excluding the energy sector) growing by a robust 4.6% year over year.

除“红山女神”之外，这里还出土了各种精美玉器，有玉猪龙、玉环、玉镯、玉璧、玉龟等等。玉器饰物与“女神”相伴，不由引人遐思：中国古代的女神形象主要集中在女娲、嫦娥、洛神、湘妃等一些传说中的女性身上，她们虽是“神”，“人”的一面也很鲜明，衣着服饰常常成为她们的形象与“神性之美”的一部分，这一点我们在古代壁画、文学典籍中不难找到佐证。我们谈起女娲总是人首蛇身、宽袖长袍，谈到洛神总是想到罗衣，说到嫦娥则是舞袖舒展，写湘妃更是红霞万朵百重衣。服饰在上古时期是人类文明进化的重要标志，对服饰的重视体现的是文明的进步。牛河梁出土的大量精美玉器，“红山女神”头像眼睛镶嵌的玉片，耳垂部佩戴耳饰的穿孔，都说明彼时玉饰已经成为“女神”的标配。从形体到服饰，再到玉饰，“红山女神”彰显着红山文化的文明形态与高度。
