As for human translators, the need for them far, far exceeds the number of them. Have you ever needed translation help? I sure have, but no human translator was available or was too expensive.
This is probably the real problem. Translators are payed shit nowadays for what is a really high-skill job. I have translators in the extended family who had to give up on that line of work because the pay wouldn’t sustain them anymore.
the issue is that many translation jobs will, and already are, being replaced with 'proofread machine translation output' jobs that simply don't pay enough. translation checking is careful, detailed work that often takes almost as much time as translating passages yourself, yet it pays a third or less of the rate because 'the machine is doing most of the work.'
An adequate AI translation is a lot better than no translation.
e.g. Italian citizenship can cost as much as a brand new car in Brazil and almost half of that cost could come from certified translation hurdles.
