CI/CD systems will automate the heck out of everything, and there will be less and less visibility into what's running where and how.
"Cloud Native" applications designed around microservices with well-defined interfaces and running in some PaaS "somewhere" will become the norm. I sadly foresee that developers themselves will be expected to become microservices, basically expected to do one thing only, and one thing well, and forbidden to look beyond their immediate horizon of the ever rolling Agile backlog. There will be less space for creativity at the individual level, and massive invisible machine learning software running in the back-end of the datacenters will automatically generate "facts" for the suits in charge, and possibly even stories on a backlog based on those facts. In 20 years, they'll generate their own code.
