It is a possibility. But I also think we're underestimating the human need to create cool, unique things. Like yes most of the projects in this situation will have "average taste" but most of the projects out there today already do. Very few people have true taste and I don't think we're just going to see them disappear or be satisfied with LLMs feeding them "average taste." They will either likely stop using LLMs if that is the case or find ways around it to make it do things the way they want to, hence preserving their taste.
But I think it is a bit of an overblown fear that LLMs will just kill creativity and innovation in coding. Hackers will be hackin
