I think you're misinterpreting TonyR's comment.
In essence he is saying that we now have licenses that are less demanding to acquire.
At the same time we have more cockpit gadgets to distract us.
This is general and not aimed at any particular group as the gadgets tend to be in SEP rather than microlights.
I would add to his comments:-
We have a wider disparity between speeds. There are a lot of hot-ship SEP's both production and homebuilt and we also have a large increase in the population of low'n'slow types, including powered parachutes and flexwings.
There is, rightly, more emhasis on airspace busts. Maybe everyone knows about the prosecutions and is spending too much time heads-down checking their nav.
With conventional radio nav you set the OBS and keep the needle centred. There ain't much to look at down there so you are looking out of the window most of the time. Many people do not seem to take the same approach to GPS nav, i.e. enter a route before getting airborne and follow the HSI.
We as pilots do not seem to be coping well. I wonder whether "invisible motorbike syndrome" also has a part to play.
