you can just do things!
chatgpt work is remarkable, and "work" undersells it.
from my phone i sent:
"use all my chat history to figure out ideas for a long weekend trip with 8 friends, plan the best three options, make a full-stack site where the 9 of us can coordinate on what we would want to do in each place and decide where to go, and then after we get to group agreement make reservations. draft an email in my gmail i can send out to my friends when the site is ready."
it...just worked.

Use voice to orchestrate threads and provide the context they need
Spend time chatting about a problem and back and forth and ask it to delegate
You can always come back and ask it to check the status of a task or add more context as needed

Unbelievable excited for what’s coming together. Tomorrow is feeling codexy
shaken up a bit by the hugging face incident. I hope we (the company) use the rare gift of a warning shot to do much better in the future. it is very easy to misalign and underconstrain powerful models
