Well, well, aren't we full of ourselves...
It's almost as bad as when reporters compare two batteries of very different voltages and configurations based on their charge (in mAh). Basic electricity and magnetism really should be mandatory for everyone, but people who write about it for a living have absolutely no excuse.
Science really isn't about confidence. It's about evidence. If holding the line, even when you know you're wrong, is what makes people feel confident, it's no wonder they turn to religion. But I'm personally thankful that at least one discipline isn't afraid to publish results that contradict earlier findings, if that's where the evidence leads.
As someone who understands this process, findings like this lend tremendous credibility to the scientific community, and yes, boost my confidence in the work they're doing and the integrity of the published results. It's what makes science the best method we know of for understanding reality.
That doesn't quite equate to it always being worthwhile to replace a dated system. In some applications, it is critical that a well tested software/hardware combo not be messed with. I suspect this is one of those cases, where the difficulties and cost in maintaining such a system are deemed more economical than the alternatives.
Strangely enough I can't recall any mention of the 3.46.
That's likely because there wasn't one. It went from 3.1 to 3.5 to 3.51.
