For years DeBeers and other diamond moguls have run extensive propaganda campaigns to try to convince people that lab-grown diamonds are physically, emotionally, and morally inferior. They had a lot of success at first. Based on lobbying, the US FTC banned referring to lab-grown diamonds as "real", "genuine", or even "stone". It required the word "diamond" be prefixed with "lab-grown" or "synthetic" in any marketing materials.
Technology kept improving, economies of scale applied, and consumer demand eventually changed the balance. The FTC reversed its rulings and in 2022 demand for lab-grown stones (at small fractions of equivalent natural prices) is at an all-time high.
Artists (and writers, and programmers) can fight against this all they like, and may win battles in the short term. In the end the economic benefits accruing to humankind as a result of these technologies is inexorably going to normalize them.
