will.i.am isn't sure whether music can continue on as an "industry", despite being in the business since finding fame with Black Eyed Peas in 1995.
Speaking to an audience during a Cannes Lions event, the musician said: "Music will always be music. Whether or not there is an industry is questionable.
"I don't really know how we make money moving forward because of the tsunami called mad tech - there was mad men and now there's mad tech, it transforms everything."
Heated debates have been rife recently about how stars and artists will benefit from online streaming services, most recently between Taylor Swift and Apple Music.
Swift slammed the new service for offering a free trial period to users where the artist would not then be paid, and her argument was heard by the tech giant who eventually changed their mind and agreed to pay during the trial period.
will.i.am agrees with the problem, saying: "It toppled our industry to the point of, how do we make money?
"People still listen to music more than they ever have before, but we have no hardware of our own."
Despite those fears, he remains passionate about making music and is excited about discovering fresh artists.
"What should really happen is The Voice should be me, Pharrell Williams, Madonna and [singer-songwriters and producers] Ester Dean and Dr. Luke. That would be a sick show because Madonna has a label, I have a label - we'd all be fighting over who's going to sign to which label" he said in a chat with Hello! magazine.
