True. OTOH - if the incident rate is ~8/year, out of ~4e7 commercial airline flights per year, and designing seats capable of 0/year is proving difficult - maybe mere improvement would be a reasonable strategy? Available resources are kinda finite, and burning phones on aircraft are obviously not on the "World's Top 100 Human Safety Threats" list.

I'd be pretty surprised if this was a popular point of view. But it is your point of view and I respect that.
