Yes, why wouldn't it be easier to transcribe and translate, skills humanity had for centuries, compared to LLMs that we've only learnt to build these last few years, and even require a frikken computer to do? Of course one of these is harder than the other...
Look at it from this lens: translating and transcribing these stories hasn't happened for the centuries they existed, while as you point out the skills where always there. In contrast LLMs have been here for a few years at most and everyone and their dogs are trying to get in on the "race".
With absolutely no insight into why, which one has better odds to happen first is obvious to me.
