I'll acknowledge that "have to" is maybe an exaggeration, but it's definitely going to be cheaper to hire new talent than reskill existing engineers (who may not even be interested in reskilling), and profit margins generally dictate the cheapest path forward in an ultracompetitive industry like logistics. And on top of all those issues, the existing workflows must be maintained while the cloud-adapted ones come online, and in a complex enough enterprise environment we're talking about a project that can take years to execute.
