Only if you need pro features. M2 would be more than enough even in 10 years from now perspective. M4 on the other hand will have you covered for next 12-14 years of use.
OLED is questionable stuff. Unless you are really into “black blacks” and stuff.
If I decide to pull the trigger I would probably go with basic Air 13’. I am not into Apple Pencil and all the additional features. Sure M4 is better but I haven’t even found anything to challenge M1 on my Macbook, I don’t see any reason that it would change. AI/ML is questionable, at least for my use cases
