With the rapid advancement of technology, expansion slots in computer systems seem to have a bright future. We may anticipate more changes to PCIe, a standard that has already undergone several generations with the goal of enhancing performasatta king allnce capabilities, as data transfer speeds and bandwidth requirements increase. More lanes and faster throughput rates might be added in later versions, enabling previously unheard-of performance levels in demanding applications like virtual reality, gaming, and data-intensive jobs. Also, as computing demands change due to developments like machine learning (ML) & artificial intelligence (AI), there might be a rise in the need for expansion cards made especially for these uses.
