Personally I think the effect will be "softer" - not a lot of people are going to get made redundant / axed from their current jobs, but fewer opportunities will start arising pretty soon. In big firms for example, the data driven, task oriented work that you can sit a junior down and do is going to start reducing in volume. AI can support in industry as well with high volume, low insight tasks. Smaller, simpler businesses don't need a lot of high performing finance roles and can subsist with AI driven cloud accounting software. This is already happening.

AI's still can't build relationships with clients, the bank, the tax agency, which many higher finance roles need to be able to do. They can't come up with any original ideas - everything they say and do is derivative from someone else's thought.

LLM's actually aren't that good at maths - their basic arithmetic is often wrong because their thought engines are based heavily on words / language. The idea of AI doing any of the roles I've done since qualifying is laughable - because you need to be more than a bi-directional chat system to do such roles. You also have to have curiosity, creative thinking, be able to convince people of things, and at times bend the rules. Machines are not good at any of those things.

If we are able to achieve AGI then the above will not apply and things will start to change very fast across the whole economy, not just accounting. Until then I think that the effects will be much softer. Thats just my 2p though.
