The discussion centers on the misconception that BJTs are universally cheaper to operate than FETs. It emphasizes that such comparisons lack merit without considering specific circuit applications and the types of transistors involved. Circuit design plays a crucial role in determining the appropriate transistor choice, as BJTs may be advantageous in some scenarios while FETs excel in others. The conversation highlights the importance of understanding the context and specifics of each application, including the differences between JFETs, MOSFETs, and BJTs in analog circuits. Ultimately, a blanket statement about operating costs is misleading without detailed analysis.
