This is akin to asking the CEO of Exxon and a Climate Change alarmist about climate change.

The CEO might seem more level headed because the more outlandish or accelerated timelines predicted by the alarmist are very likely wrong, but at the end of the day they will always dance around the safety issues because their motivation in power and profit.

The alarmist most likely understates the near term and less outlandish problems by hyper-focusing on the worst case scenarios.

We should listen to both, but probably pay more attention to those who fall somewhere in the middle on the optimism/pessimism spectrum.
