Yes ... but on the other hand, why keep reinventing the wheel? As some may be aware, if I get involved with any kit at all these days, it tends to be what we might call "retro era" stuff ... and I'm constantly amazed how "right" that old stuff was (and is).
In my humble opinion, much of today's kit is brought (booted out?) to market in a tearing rush, and then "developed" during service, at the expense of all concerned (does that ring any bells?).
Many so-called systems are not designed (or so it would seem) as a homogeneous whole at all, but are more likely to be cobbled together from clever circuity devised by wizards in San Diego, bunged into a plastic box in Shenzhen, and then stuck on top a rolling stand in Hemel Hempstead (or wherever). Not to mention technical documentation* (if, indeed, this exists at all) in some sort of weird
patois "English". All supported by an office in Chennai, needless to say. Is this really progress?

And I would suggest that it's the same with the management of technical support. Most (if not all) of the problems were solved quite satisfactorily many years ago. The only things that have changed are matters like shorter working hours, "new technology" and stuff like that. That is, the tools may be different, but there remain only so many hours available in the working week.
In our line of work, the other big changes have been:-
1) An explosion in the amount of kit found in hospitals (and, don't forget, out in the "Community") ... but no corresponding increase in resources with which to maintain it all (in other words, having to do more with less).
2) A tendency for the kit itself to be more reliable (but, alas, also less easily repaired when repairs are needed). There is some very clever kit about (some of it needlessly so), but there still remains a fair amount of ... er, crap (even though it is supposed to be "medical").
3) Ever increasing regulation and interference from so-called "management" (who seem to have Gone Forth and Multiplied, as well ... pity, though, that they saw fit to er, Come Back)!

Technical documentation from circa 25 years ago is definitely of superior quality to that generally found (if at all) today. I have many examples here ... and get great pleasure from reading bits and pieces from them. You can actually learn from those old manuals. On the other hand, some of the modern stuff I have seen has been little more than sales literature.
