<blockquote>Infrastructure. It’s all the stuff you don’t think about, the stuff that works until it doesn’t, and then your tube of personal lubricant turns out to be full of toothpaste or you end up knee-deep in chocolate milkshake. That’s not the fun kind of surprise, and it’s not a random example either. I’d had a lively morning, and I was hoping that the afternoon was going to be more on the calm side. At least with the replicator I was working on there was no obvious mess to clean up, though I wouldn’t know for sure until the skeleton key had finished running and I could rummage around inside it and see what it had choked on.</blockquote>
