SAP
“SAP built the most successful vendor lock-in operation in software history — 440,000 customers running mission-critical ERP systems so deeply embedded that migrating feels like performing open-heart surgery on a running patient. The beautiful irony is that their greatest achievement — making themselves impossible to leave — is also what makes them impossible to modernize, turning every AI integration into an archaeological expedition through 50 years of ABAP code and German engineering philosophy.”
