And what's wrong with that (old browsers/users)? Software changes not to make it easier or more logical for the user but to continue extracting money. I use Autosketch for DOS to do my technical drawings. That's from 1993, but it has everything I need to do quite sophisticated drawings.
Someone designed a "spirit level" for blind people to use, it was a ball bearing on a track that got wider in the middle, so when the shelf was level, the blind person could feel the ball was in the center.
It depends on your definition of quite sophisticated drawings and what you need😉
Having used AutoCad since 1986 and then using Inventor also for the last 18 years or so, things have changed quite a bit. When you can model a suite of 15 or however many components and make a single change to one parameter which updates all the models and their corresponding 2D drawings you appreciate how far things have changed. In seconds sometimes.
Alvin Toffler comes to mind.

@tobydog: OK, so I looked up Alvin Toffler, and you probably wouldn't consider my drawings to be sophisticated. But there's a difference between genuine advances and cosmetic. Your automatic updating example is a genuine advance, but far too often I find that software has changed yet is no better than before, just a new facade, a new price tag, and sneaking incompatibility with older versions to force people into purchase. Logically, if software is developed that does the job, it will be sold once and once only. How, then, will the company that developed it continue to make money? By claiming technical advances. How many people use spreadsheets to do anything other than very simple accounting? Yet new versions keep appearing, promising better graphics etc. Ephemera. I use spreadsheets to analyse data sets captured by oscilloscopes, typically 10,000 points, and then a load of calculations. Do later spreadsheets work any better than old? No. The fundamentals are unchanged and despite claiming to be able to handle larger data sets, attempting that brought a supposedly much more powerful computer to its knees. So I stuck with the older spreadsheet because I didn't like the facade of the newer version.
Go into a mechanical engineering workshop for making prototypes and you'll find something rather interesting. There will be lathes made in the 50s and 60s fitted with digital read-out (DRO). DRO is a genuine advance and wonderful, but why aren't the lathes newer? It turns out that modern lathes are not made as well as older ones. 3D printing is a genuine advance, by the way.

Our Inventor updates are due any time now, then annual shuffle the menu and commands around are going to happen again..😉
You're fortunate that you've been able to utilise software from long ago that suits your needs. I started designing injection moulds in 1979 on a drawing board, in 1986 the company bought a cad system, AutoCad which was basically 2/3 D, it was a bit of a learning curve but worth it. A year or two later I remember seeing a McDonald Douglas demo of their 3D modeling software system with a price tag of £250,000. It was way out reach for the company, but was what would be needed in the future.
In the mid 90's, 3D cad cam surfacing/solid modelling became affordable. It's a necessity now in mechanical Engineering. In the last 30 years every company that I have worked for or known would not have survived without the improvements in cadcam software.
I'm well aquainted with mechanical engineering and none of any of the companies that I know have any machine tools dating back to the 50's or 60's, the ones that had went out of business years ago.
We have a few Formlabs 3D printers in the office at work. They're quite impressive.
Finally got exactly what I've been looking for, for ages ...

It depends .... when the other end of the pipe is mounted to the air intake of your V8 big Block ??!?
And now...back to pictures that make me laugh.
