Most software devs won't make it to 67 unfortunately.
Without a major (really major) cultural shift in the job market mid 50s seems to be about it for most software devs - by then ageism and burnout (which happens among others because of ageism) show most tech workers the door.
When companies talk about diversity they don't mean age diversity...there's no virtue signaling in hiring a mid 50s white man.
This maybe less of an issue in Europe but its still an issue there for sure, this is a young industry that likes young people, tolerates middle aged (40-50) and hates anything above that.
