But maintaining your own separate language, computer or otherwise, imposes a cost, it's not clear why the cost of that choice should be shouldered by the rest of the world.
In general, I think having separate languages divides the world and they are a net negative, despite their role in local culture we shouldn't be trying to keep them all around.
The choice of English as the current lingua franca of the world isn't really fair (nor certain), but there is no choice that is fair to everyone, and English seems to have significant adoption already.
