It's going to be an interesting decade. ARKG is probably the least understood of them all.
That's largely the point of the ETF though, right?
Total speculation on my part... but I would predict that the average life span is pushed to 100+ by 2050. Largely on the back of genomics.
Differentiating life span and health span is worthwhile here. It might not be great to live to 100. But if your quality years (health span) are increased it will be. That is the primary promise of genomics, secondary is life span.
