Re: no backup strategy, SMH stupidity
Do you have backups for everything you've ever bought for personal use, no matter how inconsequential the purchase was and how minor an inconvenience a failure would be? I seriously doubt it. This was not a person who set up this system to provide life-critical services to a client who required extreme fault tolerance; it was a person setting up some conveniences in his own house.
Answer this question: where is your email handled? All your accounts, every one of them. Is it all on your own mail server? Congratulations. Now that server, it's on hardware you control, right? Nobody else is running it? And that server is in a building you control, and by control I mean that you own it so nobody can lock you out, right? And that server has a backup which you also own, in a different building in case the first one burns down, and you control that building too? And the email address that owns the domain for those private servers is also controlled entirely by you in the same way, so you can't be locked out through that channel either? My guess is that your personal email does not have this level of backup, and it probably falls far short of that ideal. I have taken a couple steps in this direction, but I don't have that level of control or certainty. Yet, our email is far more important to our lives than smart lights, if we decide to buy them.
By the way, if you actually have this level of control over your email, consider other services that you also rely on. Can you honestly claim to have redundant backups for everything you rely on, not just the most important ones? If you do not, then your criticism of this guy applies to you as well. Fortunately, it's unwarranted, and I don't think there's anything wrong with you or that you should spend the next few years overcoming that humiliation.
