That's a bit of an overly broad statement.
I have several times at work done projects that use FPGAs to do things faster than a computer can do, e.g. some specific processing of a full 10Gbps UDP stream, which is much easier to get 100% reliable without packet drop in digital logic than it is in software land.
The FPGA+CPU combo allows you to do a LOT of things. I tend to use just a straight Zynq so I already have my memory buses wired up from processing system to digital logic, but this is an interesting architecture.
