- Neural networks cannot comprehend complex concepts or engage in abstract reasoning like humans can.
Misconception 4: Neural Networks Are Only Used in AI
An often misunderstood notion is that neural networks are exclusively used in artificial intelligence (AI) applications. While neural networks are commonly applied in AI, they have a wide range of applications beyond this domain. Neural networks are utilized in various fields such as computer vision, natural language processing, finance, healthcare, and many others.
- Neural networks are extensively used in image recognition and object detection tasks in computer vision.

Misconception 5: Neural Networks Will Replace Human Jobs
There is a fear that neural networks and artificial intelligence will lead to widespread job loss. While it is true that AI technologies, including neural networks, can automate certain tasks, they are not meant to replace human jobs entirely. Instead, these technologies are aimed at augmenting human capabilities, improving efficiency, and facilitating decision-making processes.
- Neural networks can automate repetitive and mundane tasks, freeing up human resources for more complex and creative work.
- Neural networks can assist humans in data analysis, decision-making, and problem-solving, but they cannot replace human expertise and intuition.
