Major cloud providers have already extended useful lives in 2023, framing the 5-6 year debate: Alphabet moved servers and certain network equipment to 6 years, Microsoft extended servers and network gear to 6 years, Amazon increased to 5 years, and Meta extended servers to 5 years, all reducing depreciation expense.
