Can 128-bit TripleDES encryption be broken ?

A co-worker was arguing with me last night that 128-bit TripleDES can be
broken with today's computers. I am wondering if the co-worker was guessing
or there is evidence that TripleDES can be broken by brute force ?

According to the latest Verisign report, I see that 128-bit encryption key
would take 0.25 sextillion years to be broken (2005 reports by Yankee
Group).
