Years ago electronic components died from heat, specifically time at temperature. As semiconductors became more prevalent heat killed the high power components and inrush/voltage spikes became the major culprit for lower power components. In today's world most electronic components fail from inrush/voltage spikes but the mean time between failure and cycles to failure is much longer than in the past. Most electronics are more likely to become obsolete than fail. If I lived in an area as described by @Coyotefurharvester I would lean towards shutting off. It is one thing I can control.
