> The stuff you did in software 20 years ago has absolutely nothing to do with the stuff that's being done today.
Not even remotely true. Most of computer science is built on the past and either composed into something new upon a previous foundation, or a poor re-implementation of an already existing idea. A trendy favorite of many at the moment, Go lang is a good example of the former. For instance, CSP used in Go (and Clojure) is definitely not a new idea and has everything to do with what we do today. Another example is data structures - not sure what you're doing if you aren't using these, but the most common ones were invented long ago and most newer things I see are just refinements, additions, or behavioral changes on what existed before.
Speaking of Clojure, functional programming and Lisp are additional examples of old things "we" used to do in software 20+ years ago and are very much relevant today. You are making blanket statements about research, practices, and more here. It's true that Lisp was not widely used in many circles, but there are numerous reasons for that beyond what you mention, many of which were not good ones. Many people outside academia used a lot of old concepts successfully or otherwise knew they were good but had other limited factors, most commonly hardware or market share.
I encourage anyone "inventing" anything new to simply dig through old research whether it is 60s Lisp weeny stuff as you describe or Plan9 or anything else before you think you invented something. 99% of the time someone has at least researched it, written about it, and maybe even implemented it better than you will. Timing is often everything, as are other factors like technological resources (hardware, people, market skills, etc.). Computer science, like many fields, excels at reinventing things poorly. It usually comes down to thinking before acting as very few of us are both smart enough and talented enough to produce something properly acting on impulses and limited knowledge alone.
> This is the drag&drop and copy-paste as an abstraction VB shit era.
And this has changed how? Look at what a lot of people use Google and Stackoverflow to do. Of course these tools are great, but so was the VB GUI designer. It's how you use it and who is using it. We have far more copy-paste style tools than ever before and far more languages that are suited to producing unmaintainable spider webs of awful.
> People were writing C and the major problems of the industry were how to fit shit in to x MB of ram and x CPU cycles.
What are you doing now? People are still doing this constantly, not only for embedded programming but for games, apps, everything. Just about every month there are multiple posts on HN about people patting themselves on the back for shaving memory and CPU cycles off their code on a new platform and/or running on something like commodity hardware. I know you want to say hardware wasn't as good, but it's also been my experience less people know how to manage performance properly and we still spend a lot of time cleaning up messes, only they are on the gigabyte level instead of the byte level.
> Security was abysmal - you didn't even have process isolation on OS-es.
Not all OSs worked this way. True, the popular ones were often pretty bad. They are still not good and with more stuff accessible faster remotely, even more malicious actors, and bigger consequences, the situation is arguably worse.
> Unless you were at one of the cutting edge places that were actually innovating back then in terms of process and stuff there's likely nothing from that skill set that transfers on to the problems that we are dealing with today beyond the CS grad basics.
The same holds true today. If you only do one thing, you won't be good at programming except perhaps in that narrow field if you are lucky. If anything, it's been my observation that far less people know what they are doing as the barriers to entry into the field have gone down. Not everyone who once upon a time wrote C, COBOL, Lisp, Fortran, or whatever else learned nothing along the way. Plenty of people pivot and do amazing things.
Overall, it sounds to me you are the one who lacks the depth and breadth of experience. You need to meet more people, keep an open mind, and do research before you make judgement. Moreover, you need to avoid blanket statements (appreciate the irony).
