HIPAA doesn't require any certification either. Some organizations voluntarily choose to earn certification from private companies that offer certifications for compliance with HIPAA privacy or administrative simplification rules but this is completely optional.
For doing some reporting stuff internally, there isn’t a certification. But there are definitely humans who have to certify financial statements and communications for financial offerings.
If AI is really as wonderous as everybody says, why didn't all the employees of all the AI companies simply type "Claude, file my taxes for me" as a prompt and walk away?
Because having to ask suggests that the AI didn't already do it for you pre-emptively.
If you're not yet waking up to AI completing tasks for you that you didn't directly ask for, you might be falling behind the curve. A good personal assistant does what you ask, a better personal assistant knows what you need before you do and has it completed before you reach your desk. AI is already starting to reach into the latter category.
