If you buy used equipment which doesn't have Ethernet or your company wants you to ise the stuff that is in the Lab since 10+ years there's simply no other choice. Or companies that see Ethernet as a potential security attack vector. It's indeed not that GPIB is better than Ethernet. In tiny aspects that's argueable, but as general statement true.

It's sad how true this is. VXI gets corporate IT all prickly. An airgapped lab network would be safer but somehow they hate that idea even more.
GPIB isn't even on their radar. Test to your heart's content. It's not a "network".
