This born in '69 53 year old right here is programming backends and frontends for websites, and PySide5/6 Qt5/6 applications.
I'm still sharp as a pin.
Like you say, there has to be some point at which those younger than I stop thinking someone in their 50's isn't as hopeless with technology as they assume.
Of course not everyone in my Gen X'er group will be like me, then again, I know of folks in their 20's who struggle with anything IT.
Quit with the ageism, people. It's getting old ;)
