Everything is software now. So much firmware (which is software), and so much hardware that cannot run without software. Your refrigerator, your dishwasher, your car, airliners -- the trend is for everything to be software now.
We can build reliable software when we want to. It just has limited scope and/or undergoes more expensive development procedures.
It is easy to build a finite state machine for a dishwasher that is fairly reliable. Likewise, consumer jet code that hits safety considerations is heavily tested and audited...and the FAA cares about it whenever it causes a plane to crash, leading to a lot of regulations on how the code is vetted.
