Donahoe made the remarks to Bloomberg reporter Emily Chang, after she asked him whether eBay has any plans for delivery drones.
"We're not really focusing on long-term fantasies," Donahoe said. "We're focusing on things that will change consumers' experience today."
"So you think it's a long-term fantasy?" Chang asked.
"We'll see," Donahoe said with a shrug.
eBay posted revenues of $14.1 billion last year, while Amazon generated $61.1 billion.
Amazon CEO Jeff Bezos made the announcement that the company had started experimenting with autonomous delivery drones in a "60 Minutes" interview. He said he expects the drones to be fully operational within four or five years.
