Current language generation systems have made significant advancements in recent years but still have some limitations. Some of the key limitations include:

  1. Lack of Contextual Understanding: Language generation systems often struggle with understanding context and generating coherent and contextually relevant responses. They may generate generic or illogical responses that do not fully address the specific query or context of the conversation.

  2. Insufficient World Knowledge: Language generation systems heavily rely on pre-existing data sources, which may lead to limited or outdated knowledge. They may face challenges in keeping up with the rapidly changing world and may not have access to real-time information or experience to provide accurate responses.

  3. Limited Creativity: While language generation systems can generate grammatically correct responses, they may lack creativity and originality. The generated text might be repetitive or predictable, which could lead to a less engaging user experience.

  4. Ethical Concerns: Language generation systems can be vulnerable to biased or unfair content generation. They may unknowingly perpetuate stereotypes or exhibit biased behavior due to biased training data. This raises concerns about the potential to generate discriminatory or offensive content.

  5. Difficulty in Handling Ambiguity: Ambiguity is a common part of natural language, but language generation systems may struggle to handle it effectively. They may provide ambiguous or incorrect answers in response to queries or generate misleading or misunderstood text.

  6. Limited Domain Expertise: Language generation systems may lack expertise in specific domains and may not be able to provide accurate or detailed information in complex or specialized subjects. They might not be equipped to understand and respond to domain-specific jargon or terminology.

  7. Evaluation Challenges: Assessing the quality and performance of language generation systems can be challenging. There is no universally accepted metric or evaluation framework, making it difficult to objectively measure their capabilities and compare different systems' performance.

  Addressing these limitations requires ongoing research and development efforts to enhance contextual understanding, improve knowledge base, promote creativity, ensure fairness, handle ambiguity, cater to domain-specific expertise, and establish robust evaluation methodologies.
