As I was burbling on on twitter, I’m not really losing any sleep over this. In terms of objective risk I’m far more likely to get run over walking across the road to get my lunchtime sandwich than have someone tampering with my pump remotely. I don’t worry about the former, so I’m not going to worry about the latter.
It’s going to be really ironic if I get run over when I go for my lunch in about 45 minutes. Especially now I’ve written this.
