As a scientist/physicist I view microgravity as another system state parameter: in early stages, systems behavior was studied at standard temperature and pressure. Next, observations took place over an entire range. Significant scientific discoveries and engineering advances were made when observing systems at low temperatures or low pressures. There is an immense database of information specific to 1g. Microgravity would provide a second dataset to explore further values of gravity ranges...
As a pragmatic person (entrepreneur? business? maker?) I view microgravity as benefiting and improving life on Earth in almost every aspect of it as a result of the serendipitous and cascading effects originating in the new knowledge gained in space.
I hope the presentation speaks to this effect
