>I also push often because I'm forever aware disks can fail.
In the 20+ years that I've been using computers, and ≈15 or so that I've been writing software, I've never experienced a drive failure.

With the experience of the last 3 or so years of using ZFS, I'd bet most of my "still working" drives over the years were erroring and losing data by the time I replaced them, and I just didn't know it.
Personally I share the same experience: In the 30 years I've been using personal computers at home and work, only 2 disks failed on me, one was an error on my part during an OS upgrade and the second was an external disk that physically fell off my bed while I had it plugged into my notebook. So both of these weren't really those random failures.
On the other hand, while working in an IT infra team of a 60 developer company with 4 racks full of servers for 3 years, we'd get to see about one failed SSD per 2 months and 2-3 failed disks or SSDs per year in servers.
During the 1 year I worked for the IT infra team at a smaller hospital of a medium sized city with a large VDI environment and two HP EVAs in a two datacenter configuration each, we'd get 3-4 disk failures per week. Those had over 140 disk per storage each and were approaching the end of their support life, being around 5 years old, so the failure ratio started to get higher.
But those are just the catastrophic failures, I'm pretty sure I've also had hardware-related data corruption here and there as well.
