We've got IDEs that compile in a flash, compared to the interminable compiles of the past. That's a huge improvement to productivity.
We could have capability based security, which makes it possible for a user to run any code without risking any side effects to files other than the ones they choose, like being able to plug in any lamp without burning down the house... but we haven't figured out, en masse, that we need that one yet.
We've got GIT, which is a huge improvement over ZIP files of source code stored on floppy disks.
We've got GitHub, GitLab, etc... the ability to quickly and easily work from home, office, laptop and keep them all in sync, or any other coherent relation (working on a feature branch, etc) without major hassle... is amazingly productive.
We've got silver bullets everywhere.
