Totally, but I specifically meant the RJ45 connector itself! WRT other technologies, we've updated USB and Thunderbolt to use the compact USB-C connector standard. We've updated display connectors many times over the years! And yes, there are legacy installations and so on, but that's never a good reason to not advance a technology! We'd all still on SCSI connectors or SATA if legacy was a good reason not to evolve technology! Just looking at a rack of patch panels and switches, you can see a lot of space is taken up with supporting the RJ45 connector itself! None of the other comments really explain why we still use RJ45. Because it's a standard and legacy isnt a reason to not have developed a modern compact alternative!
