(CSCO) CEO John Chambers appeared for the 23rd time on Cisco Live, the company’s IT conference, with this message: the next few years will be “brutal” for the technology industry. He predicted that there will be a lot of consolidation in the IT industry, and a few big names may be relegated to nothingness within a few years.Chambers pointed out that technology has been evolving at speeds twice those seen three years ago. He warned companies: “You’re going to see a brutal, brutal consolidation of the IT industry.” He went on to add that within the next ten years, a lot of high-tech players currently in the industry will be extinct. He was pointing fingers at the big five legacy tech companies – Cisco, Microsoft Corporation (MSFT),International Business Machines Corp. (IBM), Hewlett-Packard Company (HPQ), and Oracle Corporation (ORCL) – saying a few will go belly-up within a few years.Chambers did not say exactly which of the big five tech companies would disappear, but seemed to be hinting at HP and IBM, which he said have failed to see any revenue growth in the last two and a half years. He substantiated his argument citing research from Gartner and companies’ own earnings reports.
