Bezos says 2-3 year timeline for space data centers is a 'little ambitious'

Key points

• Amazon founder Jeff Bezos says bringing data centers into space is a "very realistic" outcome, but could take longer than expected to pan out.
• "Some of the timelines we hear are very short," he told CNBC's Andrew Ross Sorkin on Wednesday.
• "People would talk about two or three years.
• That's probably a little ambitious." Bezos, who founded space company Blue Origin, said one key barrier to entry is energy, and chip costs need to come down to make more room in data center budgets.
• Launch costs also need to get cheaper, he said.
