Yes, “xennials” probably have their own generation because of this, but I have met a lot more millennials that can manage UI changes over genx.
Switch a genx from windows to Mac and they are lost. Switch a millennial and they seem to be fine. I’ve seen this with phones, TVs, websites, etc.
Genx were young during “dumb” tech. VCR, digital phones, etc. millennials were learning the internet as it was moving from a hobby to its own platform, cellphones as they were first widely available then as they went “smart”, and a lot of other examples.
Don’t get me wrong, a lot of knowledge was lost along the way like manual categorical systems including tabulation machines, phone books, Thomas Guides, even cabinet filing systems/card catslogs. Genx handles these things a lot better than the more recent generations.
