In those five or six hours, I estimate I’m able to get two or three days of work done (at my level of productivity before I started paying $20/month for ChatGPT+).

This is very comparable to the ROI I would say that I've been seeing for my programming work. I feel like a super hero, or a 22 year old on adderall. I know everything I need to do for any project, but between client meetings, executive meetings, business development, meetings with the product team, mentoring, the actual amount of focused time I get is so little. I can offload a huge amount of the "I know how to do this and I'll know if you do it wrong, but please do this for me" to the machine. This past May I took on a task that would have taken a comparable person, probably 6 months, and I knocked it out in 2.5 weeks. If you already know what you are doing, ChatGPT is steroids.
