As a senior engineer I spend a lot of time reviewing and approving technical designs, PRDs etc.
Over the years the amount of basic copy editing I have to do has really grown. I sometimes feel like I’m removing 20%+ of the text. And that was before LLMs.
For better or for worse my team has standardized on using Miro for technical designs and diagrams. It's a lot easier to visualize the system in a diagram than it is to talk about it in prose.
I think it's important to choose the right medium for communication though. Some things just need to be written out concisely.
