Software fixes can be costly, but they are easier than most other fixes at scale.
Doing a recall on a popular hardware product is orders of magnitude harder than issuing a software update for that same product.
There have been a few scenarios at my job where it was easier to just solve a problem in hardware, but once a bunch of hardware gets shipped, only software can save us.
It's easier to update the software than change the hardware. But you the problem that software can never fixed through the multiple iterations of updates - through the complex of the software and because the company pushes new features with new bugs along with the bug fixes.
But my comment above wasn't really to say software was more was less costly than hardware. It was mostly say that software is more unpredictable than hardware.
