This isn't directly on topic, but I don't like it when people say that someone "perfected" some sort of design/tool/technology. They may have made it much much much better than it was before, but is the new version ever really perfect?

Usually, in this context, "perfected" means "made good enough to actually use for practical purposes". Lots of neat ideas languish in obscurity at the edges of innovation because they're not quite "there" yet.

Most people understand this use of 'perfected' and do expect more improvements, probably at a much greater rate now that the idea finds widespread use.

Perfected might be better said "brought to the practicality tipping point?"
