Do people still use node?

I'm curious, do individuals and organizations still utilize the node system in the realm of cryptocurrency and blockchain technology? With the rapid advancements in decentralized networks and the emergence of newer technologies, has the significance of nodes diminished, or are they still a crucial component in maintaining the integrity and functionality of these systems? Is there a growing trend towards alternative methods, or does the use of nodes remain prevalent and essential? I'm eager to understand the current state of node usage and its role in the ever-evolving landscape of cryptocurrency and finance.
