For me I think the difference is that software never used to be actually important, it was either games or just otherwise hobby software.
Now when something crashes I actually need it for work, or to bank, or to navigate, or hell sometimes the only menu at a restaurant is a QR code but my damn phone is failing to recognise it again.
When you introduce technology into every facet of life, it's suddenly death by a thousand cuts when things don't work, or are a slow buggy mess.
I agree. Though some software pain used to be more intense (blue screen of death, etc), our lives have become more deeply enmeshed into software, so we feel the friction more. I think we also expect a lot more from software in our daily lives than we did 20 years ago.
Well, banking is digitalized for a long time (such a long time that they actually are using mainframes and cobol), and it's definitely not the epitome of good software, so I think it was always important, maybe we were just less directly reliant on it.
