A and B are talking about a technology.
A/B: reason 1 しreason 2 から, どうしても……ね
I'm not sure what is the supposed meaning of どうしてもね here. Also the reason I'm using A/B is that I'm not 100% on who is supposed to be saying this (because manga). I at first thought that this is B replying to state their concerns. But now, I think it's A. Stating what they presume to be B's concerns.
I think どうしてもね might be a sort of saying "Is there any other reason?/anything else" and like. But I'm not sure.
