Techs will adapt and change. At my company we are done with our laptop replacements for field personnel. The new mobile system with iPads and iPhones is fully operational.
Forums in general are on the decline. Sites such as Reddit and it's many clones are taking over because they are more mobile friendly than the current forum platform. Responsive designs have helped, but, in reality until forum software adapts the decline will continue. Speaking of this site I have a plan to adapt to the changes. In the future I see new software and a focus on the new mobile world which is still an infant.
