Google Translate simply isn’t meant to be used for dictionary lookup, though. If you use it for that then you’re using the wrong tool.

This is like complaining that Word isn’t as good as vi, which is decades old, for text editing. Sure they could bolt a text editor onto Word if they wanted to, but why bother? That’s not what people are looking for when they use the product. And if that’s what you want, there are many other choices that are much better.
