Middle ground. Compromise. You're looking at language diversity with the assumption that it's a problem. No corp, no matter how powerful, could make the be-all-end-all language because a language isn't a tool; it's the culture around the tool.
Imagine you have three teams of hackers, each composed of die-hard devotees of a language: C++, Rust, and PHP. You task each team with building a program to the same spec, in C++. You already know what to expect, don't you? The PHP bunch will finish first, with a program that works probably well enough. The Rust gang will make something frighteningly safe, that doesn't use any memory. 10 years later the C++ folks are still writing clever templates.
Different languages are good at different things not just because of the strengths and weaknesses of the language itself, but because a language has an associated worldview, and different worldviews lend themselves to different goals. Within hackerdom there are many communities adapted to different ideological ecosystems.
In a future with one "perfect" language, where would you go when safety was the only thing that mattered? You'd have to find some old geezer who cut her teeth on Ada, before the Programming Cultural Revolution.
