COBOL failed epically at its goal of making programming easy for everybody by creating an "English"-esque syntax that everybody could understand. It failed so epically that it has apparently destroyed the idea so thoroughly that you don't remember/realize that it was a first-class goal of the language.
If you go back and read what I said, notice that nobody could sensibly call Java a generalized "failure" either. It specifically failed to create a language that would be something that could be used by large groups of people easily, and to the extent it succeeded it did so with incredibly grit, perseverance, and tons of third-party tools and terribly abortive efforts over the years, and it also did it so badly that people entirely stopped talking about even trying it. This despite the fact that "how do we write programs in companies with hundreds of programmers working on tons of discrete projects" is by any measure a very large use case for programming languages, and that only Go is directly addressing this use case directly is in some sense a travesty. (Others address it indirectly, by claiming that their features that are really intended for code safety or power may also as a side effect have the ability to make big programming teams function well, if they even claim that.)
