ZURICH, Oct 16 (Reuters) - ABB is "very

confident" about future demand from data centers that power

artificial intelligence, Chief Executive Morten Wierod said on

Thursday, rejecting concerns the sector could be in an

unsustainable bubble.

"Over the next five years I am very confident about demand

from data centers," Wierod told Reuters. "I don't think there is

a bubble but we do see some constraints in terms of construction

capacity not keeping up with all the new investments."
