Infrastructure has changed a lot in years with cloud and multi-core processors. As it said the infrastructure is scalable & distributed, and dynamic has more capacity. But most programming languages can’t take advantage of the infrastructure.
For example, you have one application that executes 1 thread task at a time in order after finishing the first thread task it starts the second thread task to finish in order.
As the infrastructure has improved so it’s possible to application can execute tasks in parallel which makes the application faster.
