From the outside looking in yes, because I can't imagine not being interested in knowing more about the parts of my heritage I wasn't raised around. But if it works for you that's fine too.
He'll get to a point in life when he'll either feel left out by his peers or get super curious about his roots and regret it
When you are young you tend to follow trends and fads. Many non-american kids who grew up in the U.S.A. in the 80s and 90s were made to feel as if their culture (latino, caribbean, african, etc) was inferior to that of americans so they felt the need to FIT IN in school thus rejecting their own cultures and language. Back then if you weren't "hiphop" you weren't sh!t.
As a result you find many latino kids who barely speak any Spanish. I personally know many kids born to Haitian parents who fell into that trap. Many others caribbeans too.
But ever since there has been a change in tides and people are taking pride i their own cultures and also they are getting older and want to know more about their roots. Al the sudden you have them scrambling to learn their culture and make up for lost time because they find out that as bad as they wanted to be American, they'll never ultimately be considered "american" so they need to familiarize themselves with their roots so they can understand who they are and why they like the things they lie and so on and so forth.
- I know a Costa Rican chick in NY who is like that. She and I met in CR and had fling. She's in the same boat. Doesn't speak a lick of spanish.
- My own cousin from NY told me he regrets he never learned kreyol too but his kernel is decent at least so i'll give him a pass but he has no clue about haitian music
- This chick i know from Dominica (La Dominique Island) never learned kreyol because she grew up in the virgin Islands. Now she's trying her hardest to learn it
- And yesterday i met this dude and his wife at a Haitia restaurant. His wife is black-american. His parents are Haitian. He doesnt speak a lick of kreyol and feels left out in conversations now when he visits old friends and family. He claims he "understands" kreyol but just doesnt know how to speak it. I told him There is a Rosetta Stone for kreyol. Dude was so excited about that.

People like this will feel left out of many social environment because not only conversation but culture and music. They'll go to festivities of their ethnic group to fit in but find that they are far behind. They are not familiar with popular and classic songs of their culture so
Don't be that dude,
@observe. Get with your peoples from time to time. You may not be into it (yet) but you need to take part in it
