...I can understand the mentality of "Boomer"-types and their avoidance of computers because of how life was for a majority of their life and suddenly there are all these new complicated things to learn....
I'm not sure that you have the mentality of 'boomer-types' quite right, since we were, largely, the generation (or so) that drove adoption of microcomputing, even to the point that many of us played a significant role in development and systems engineering. It is frankly a bit alarming, certainly too simplistic, to think of the boomer generation avoiding computing because of all the new and complex things to learn.
To my mind the issue is a somewhat different one than this, because to some degree I think the reason some of us are 'stuck' in the older generation(s) of technology isn't a resistance to the new, but a belief - or recognition - that where we were at in a previous iteration of the technology was simply better for our needs than it is now, in the sense that then it was less complex and over-developed, thus more finely tuned to what we we were using it for.
The problem as I see it is that many developers and systems engineers today never really saw or were exposed to the IT landscape as it was in the late 20th century, and so don't appreciate what those technologies could do. The present-day dismissive attitude towards early 90's computing, for example, ignores the fact that these machines were core productivity and management tools in businesses large and small at the time and for years after, and are just as capable now as they ever were then. Where today, it is common currency that if it can't 'do the internet' it is useless, many of us actually see this as a benefit.
For example, I can personally see a huge benefit in a portable which can run 24-hours on one set of 4 batteries, is simple and fast to use, has a first class keyboard, and rock-solid basic functions. That it doesn’t need updates, patches, has no end-of-life OS to consider, and actually does ‘just work’, is a huge positive, and the lack of email, messaging and internet is advantageous in a number of ways, not least that there are fewer distractions, almost total data security, and zero risk of malware. I used exactly this computer for years for Information Security project work and technical documentation, and it was perfect where a modern device with modern OS would not have been.
The point being, not that as a boomer I grew up without computing technologies and so have a resistance to it or reluctance for it, but that I saw what I believe to be the best of these technologies, before they ballooned into modern monstrosities which I have to serve rather than have to serve me. And really, I don't think I have ever known someone my age who resisted these technologies, though I have known quite a few who can see the fallibility of reliance on some of the more recent developments or use of them.
