* Age (why do older people always assume their prior experience in stone-age computers informs modern age computing? Sometimes it does, but often it doesn't)
The contra case is: amazingly large number of truisms found in the 50s 60s and 70s hold true today as well.
* Experience (why do experienced people always assume you can explain things to inexperienced people? Some things have to be experienced to be understood)
The contra case is that some uplifts can be done, and don't have to be experienced. But how to decide which ones?
So this men clamming up thing can be at least two other reasons for holding schtum: Maybe its not about mars/venus but is about age and experience concerns?
