Not having attended any meetings since about 2001, for reasons of safety (sounds a bit dramatic but I don't like my wife being out on her own late at night where we live now), I have started accompanying her to the mid-week meeting.
When I was young, the ministry school and service meeting were central to training brothers to take the lead. You were assigned instruction talks, then if you cut it, you moved pretty rapidly to public talks - a full 55 mins at the time. I was just 18 years old when I gave my first public talk and this was a first step to moving rapidly through the ranks. I was only 19 years old when I was appointed group study conductor, in those days a key teaching role as you had the opportunity to interact with a relatively small group of publishers.
I was so surprised to find how different they are nowadays to when I was 'in'. No instruction talk, all the parts carefully orchestrated by head office, no room for any of the elders to put a personal or local spin on things. So, it is very apparent to me that the GB are not particularly interested in training speakers and teachers any more. Whilst I don't expect they will become a totally internet based religion with no meetings, I do suspect that in future all parts will done as pre-recorded items from head office. Elders will no longer be primarily teachers as such but merely 'enforcers' tasked with making sure the flock keep in line with whatever is dished down from above.
