Consider the example of autonomous vehicles. These systems rely on big models to process vast amounts of data from sensors and cameras. However, they still struggle with edge cases, such as unusual weather conditions or unexpected road obstacles. In these situations, human drivers often need to take control. This highlights the gap between the promise of full autonomy and the current state of technology.

Another area where big models fall short is ethical decision-making. These models lack the ability to understand context or moral implications. For example, a model used in hiring might inadvertently favor certain groups if the training data contains biases. Without human oversight, such issues can go unnoticed, leading to unfair outcomes. You must recognize that human judgment plays a crucial role in ensuring these systems operate ethically and responsibly.

The misconception of full autonomy can lead to unrealistic expectations. Believing that big models can function without human involvement might result in poorly designed systems or failed projects. To avoid this, you should view these models as tools that augment human capabilities rather than replace them. By combining the strengths of big models with human expertise, you can achieve better results and address the limitations of current technology.

Tip: Always include a plan for human oversight when implementing big models. This ensures that the system remains reliable and adaptable to real-world challenges.
