This depends on your area, and your ISP. If, say, you use AT&T and you need Internet for your job (WFH?), redundant Internet is crucial. It's not exactly "minutes" they are out. (Their outages states are often "meh, we'll get around to it in a day or so", figuratively) If you live in a rural area, even more so. You're not high priority for fixes in the first place. (And AIUI, the author lives somewhere in rural Texas) Do you need to run it as high tech as that? Probably not. My alternate Internet is my cell, tethered. (And if that breaks e.g. during travel, yes, I have a second cell with a separate provider, because heaven forbid the US had consistent cell coverage) And most of us probably don't give a damn about e.g. 1,000 year photo retention. Or many of the other things he's doing. But it sure is fun if it appeals to your personality, and you can afford to keep it running.
