There is a paragraph in the interview that speaks of bringing down the cost manufacturing vectors yet I take the proposal as spurring innovation, adding greater focus on delivery.
The enterprise value of select companies will change dramatically once the IP is proven actionable, licensed, and accepted by industry as cutting edge.
Typically, and in this case, the "vector" is the delivery package used to deliver a particular gene sequence to the targeted site.
When you say a company has >100 vectors, I assume you mean they used one (or maybe two) vector to package any one of a hundred different gene sequences, not that they have >100 different ways to deliver a particular gene sequence into a cell or organ.
If their approach to gene delivery doesn't work well, or isn't protected by patents, it isn't worth much.
