I don't think there is enough of an incentive for everyone to adopt these technologies. That's where legislation comes into play.
This is what happened with the cosmetics industry in the European Union. When the EU government said that they were no longer going to be able to test on animals within a certain period of time, the innovators, the companies, the researchers and the government came up with a plan on how to accommodate that.
Right now, we have issues with “validation”. All of the new data that are generated from these new methods are constantly being compared to the old animal methods. That's hindering our progress. Even the ones that are far advanced are not being adopted by regulatory agencies around the world at the pace and scale that they should be, so that is holding us back.
With legislation, we could enforce that and give them an option to do it quickly.
