Some people have raised the issue of Elon Musk's stance on climate change.
Keep in mind that electric vehicles have been an area of high interest to Elon since his college days and maybe before that.
If he has to believe in climate change for the project to have a chance, he will.
Similarly, the famed geneticist, George Church also has to believe (or at least tell people he does) deforestation in Siberia is good for the climate if he wants to have the opportunity to resurrect the Wooly Mammoth.
