I think speculating about the future/development of MA is as pointless as 1yr students trying to figure out thow the next lineage holder will be in their style.

What will happen will happen, most of the decisions are done by our elders and there is little we can do to influence them.
All we can do is try to become elders ourselves and try to steer the cours from there.

The way I see it, if you train hard and sincerely you will always find a good teacher or one will be recommendet.

The majority of MA out there are NOT interested in the future of the MA, most of them want either SD, health or other benefits.

Many want to become Sifu/Sensei not because they care about the art, but because they see it as an easy and quick replacements for their desk pushing jobs.

Just my Opinion.
