How problematic is AI technology?

Between 2015 and 2020 people applying for visas to enter the United Kingdom to work, study or visit loved ones would fill in the paperwork in the usual way, and that data would then be handed over to an algorithm to assess. It would give them a rating: red, amber or green. Of those being assessed as green 96.3 per cent were waved through. Those marked as red – the'riskiest' category – weren't automatically rejected, but were subject to further checks, with senior staff being brought in to check the data and make a final decision. This partially automated process, run by the Home Office, ultimately approved 48 per cent of red applications. Those using it trusted its decisions.
