I do wish intelligence had a meaningful effect on your ability to learn skills or languages. They at least allowed more languages learned for a high intelligence. It would be nice if a high intelligence allowed for more skill or tool proficiencies. I imagine they didn't want to model high intelligence having a meaningful effect on learning in this edition. This edition is meant to be played in a fast, loose fashion. If you want things like intelligence and lore to be meaningful, up to you to make it happen.
