As someone that knows a high-flying portfolio manager who works at a very well known firm that I wont name... I can confidently state these tools are DOA. Ive spoken to them at length about the nature of what these people actually do day-to-day. If you think its just about using excel then you're already way off.

They (OAI+Anthropic) very much do not get exactly what these people are doing in the job (accounting+corporate finance+valuation+asset management) and what the actual production process is. These tools are irrelevant, disrupt flow and if anything just add noise to what one is doing.
