Granted, if I get 10 years of use out of anything built in this century, I do consider it a minor victory.  So maybe that's my answer.

In which case, yes I personally do think they are missing the point of “software”, and I’m happy that our way of developing Qt is not constrained by those industries.

Those would be your customers. 30 year old security issues tend to be 
easily plugged or otherwise defended against. There is no defense 
against the relentless stream of new security vulnerabilities, bugs, and 
crashes brought about by continuous integration and deployment.

The Wild Wild West coding style really does kill people. A blue screen 
of death on your heart surgery robot mid-surgery generally results in a 
real death.

I don't have to. The Parts Order Routing System at Navistar has been 
making sure trucks have the parts and maintenance items they need to 
keep bringing food to your store, supplies to your construction sites 
and service vehicles for when your power lines go down. It is also 
keeping the fire engines and pump trucks in many/most places running, 
not to mention keeping the Blue Bird buses safe and operational hauling 
your kids to school.

The trading floor system at the Chicago Stock Exchange I first worked on 
in the late 1980s ran to 2005/6 when they got rid of the trading floor 
to become an all electric stock exchange.

You knowingly create 30 year old security issues and you diss your 
customers who have worked around theirs.

:P

You forgot customer abandonment

death of OpenSource LTS

Qt 6 being useless

QML needing to be ripped out.
