Is one of the main problems of finding a better system than taxonomy there is a shortage of kinds of plants and animals to identify?

One of the main challenges in developing a better system than taxonomy is not necessarily a shortage of plant and animal species to identify, but rather the complexity and diversity of existing life forms. Taxonomy strives to classify and organize this vast array of species, which can make it difficult to create a more effective system. Additionally, advancements in genetics and technology continually reveal new species and relationships, complicating the task of re-evaluating classification systems. Thus, the issue lies more in the intricacies of biodiversity than in a lack of organisms to study.
