Bullshit, there’s been plenty of very good fanfics that show how Equestria could of industrialised and began integrating other species like Changelings and Dragons while maintaining their cultural cohesion and national identity. A distant future where Twilight rules over a modernised nation in a more interconnected world that is welcoming to other nations but meaningful distinct is a proven concept.
The problem is there is currently a skill drain happening in corporate media because they have got tired of dealing with creatives who are temperamental, prone to scandal and inconsistent in output and tried to replace them with people that look good in marketing material, do what their told and accommodate the marketing department at every turn.
The problem is these people are as creative as a jar of mayonnaise and have only been taught to regurgitate superficial talking points that get them social approval. So all that get produced is social capital propaganda pieces that exist for the assemblers to brag about at bougie parties in gated communities, like ‘art films’ no one is expected to watch the shit, their just props for the ‘artists’ use to complete their aesthetic and for decadent rich people to throw money at so they can claim to be cultured.
Shove it infront of a audience of poor people wanting to be entertained of course it’s going to go badly, the whole modern art conceit is that its all meritless garbage that just exists as a prop for social and financial transactions.
