We need a lot of long-term studies on this new form of creating meat because of its untrustworthiness of people and the way it's made. It would be like trying to get everyone in the world to switch to electric cars all at once, even though research says electric car parts aren't doing that much better at protecting the environment than gas fueled cars. We also need to test this more because of the potential risk it could have on our body and what it could taste like, or the texture, or the cost it'll take to make something like that, or the amount of people that would distrust something like that.
