I'm not convinced by your skepticism about correcting prejudiced bias. Debiasing certainly gives the AI a understanding of the world than the original (biased) language dataset, but it's not necessarily less complete - or less accurate. After all, any one corpus is incomplete, and has biases based on the items that were chosen for it - which are likely to reflect the biases of the past, and of the person choosing the corpus. It may not be a "complete" or "accurate" reflection of today's world - let alone the future. So it's not at all clear to me that efforts to undo the bias will necessarily make it less "accurate".
