Starbucks' adoption of AI for in-house system management signals a significant threat to Indian IT service providers like TCS and HCL Tech. These firms, already reporting unimpressive earnings and shrinking workforces, face a future where clients leverage AI to reduce outsourcing and internalize tech functions. The traditional "annuity business" of maintaining packaged software is eroding as AI enables clients to build their own solutions and demand lower costs for outsourced work. Indian IT companies must adapt swiftly to this AI-driven shift to remain competitive, as their current business model faces unprecedented challenges and investor pessimism runs deep.
