I think bedrock is reasonable, and so is Prelude (https://github.com/bbatsov/prelude). I used to have a sprawling init.el, but these days is pretty compact (236 lines), mostly using straight to install packages and then configuration for gptel, agent-shell, and various hydras (https://github.com/abo-abo/hydra) to quickly execute various functions.
Especially if you don't want to use an agent to help you get started. If you're using an agent, starting from vanilla is much more feasible.
I only started using an AI to help fix issues or understand configuration problems when my config was already >1000 lines.
But yea there are several ways to approach this :)
It will be a struggle. It was around 2 months before I felt remotely comfortable in Emacs. And nearly a year before I really felt at home. It's a long road, but gradually you mold the editor to yourself so tightly that you'll never be able to go back. The remarkable thing is that the progression never stops. The tool just keeps getting sharper and sharper.
No one will ever convince me that there is something better than vim mode for editing text (or comparable modal editors).
