Old Telecom Folks, did your peers talk about VoIP the same way that network engineers in this sub are talking about SDN?

Ex: "It's overrated/a mess/just a buzzword/poorly defined/not happening anytime soon/not a good fit for my enterprise/I don't give a shit" (Ex 2:https://www.reddit.com/r/networking/comments/6fy2pe/sdn_do_you_give_a_shit/)

It seems like there are a lot of these sentiments in this subreddit, and I'm just wondering if the old voice engineers felt similarily around the time that VoIP was starting to compete against the traditional PBX systems.

Side Note: Do you know any telecom engineers that didn't adapt well to the changing technology? If so, what are they doing now?
