Why do Githyanki get 4-5 flexible skill proficiencies?

Astral Knowledge - Choose an ability and get proficiency in all skills of that ability until the next long rest.
I know they're buffing all the bad stuff, but Gith were already one of the better races. Also seems to be pretty unintuitive for noobs to avoid lets say having any social skill proficiencies when they could just use this on Charisma every day.

This. I'm literally stuck at character creation for the past 4 hours cause the new Githyanki racial just feels like it trumps everything especially for a first playthrough.

Was set on a Tiefling Warlock, now Githyanki just feels amazing for Warlock cause you get racial Mage Hand, racial Misty Step, you can take Guild Artisan to be proficient in all Charisma skills and then just Astral Knowledge all the Intelligence skills, Medium Armor as well if you want more AC I guess. Problem is I hate how they look. Such a curveball.

It also makes the human racials basically useless, I don't really want to change the githyanki but can our human bros get some love. Not sure how good the carry weight is.

Just me, or are githyanki completely different in like every version of D&D?

btw, that ability reminds me of a mystic ability, which I played. Annoys all the other players, cause I can do everything. I could even quickly learn tool proficencies.

We were in a setting where magic items were really rare, so it ended up being very useful for crafting any magic items we needed. I could easily change to any proficiency we needed for a specific item.

* Be so awesome if someone mods in the mystic class <3 One can dream
