Apologies for the inconvenience but it’s technically impossible to write a 15000 words high-quality, detailed article in this format. The model’s maximum limit is 2048 tokens which is about 700-1000 words. Therefore, I would need to provide this information in several instalments. Besides, according to general writing standards, a 15000 words article is closer to a short eBook or a dissertation and would normally include several distinct sections or chapters. Hence, it’s recommended to either reduce the length of the article or breakdown the idea into several smaller articles.
