I'm a semi-professional violinist who got to borrow a Strad for a couple months and whose long-term teacher has the lifetime loan of a del Gesu (and has had access to a Strad but prefers the del Gesu!)
I don't have Studies to back this up, but anecdotally:
* Playing fine violins takes a lot of practice with the specific instrument to begin to unlock its potential. I was scratching the surface after a couple months; people with longer-term loans say it takes years.
* Strads in particular are surprisingly hard to make sound good at first. I'd say there was a good two weeks where I sounded better on my $2500 Chinese-made violin than I did on the multi-million dollar Strad. (del Gesus sound great out of the box. This is widely agreed upon but I don't know why it is)
* In terms of pure craftsmanship there are many contemporary makers who are working as well as Strad and del Gesu, and I don't place much stock in them having access to uniquely good wood or magic varnish or anything like that.
* However, for poorly-understood reasons the act of playing a violin "opens up" the sound and also gives you access to more and more tone colors. A 300-year-old violin that's been played a lot will therefore have a much bigger tonal palette than a contemporary violin, even if any individual tone color isn't strictly better than the tone of a contemporary violin.
* The corollary is that in the year 2300 I believe top-end contemporary instruments will be as good as Strads are now.
* If you just thought "what if we simulate the vibrations of playing on new instruments to expedite their aging", you're not the first! Some luthiers hook new instruments up to a specialized amplifier and effectively play music through the violin for a couple weeks before selling it. A lot of people claim this helps a lot, but I don't have first-hand experience of it.
I own a handful of TI calculators (TI-{80, 83, 83+, 86, 89T, NSpire CAS}, possibly a few others) but actually use a TI-89 Titanium emulator on my Android phone. I no longer do anything remotely interesting with it, but I prefer it to the stock calculator since I know how it does order of operations, it shows fractions, it's easy to get old return values, etc. Don't tell me if the stock calculator now does all that; the TI-89 ergonomics are burned into my brain. (I was in an advanced math class which got me using a TI-80 at the age of 9)
Do you have examples of the dev experience degrading? My experiences is that the tools and libraries only continue to mature (as does the Clojure language itself).
Do you just mean that things are improving less quickly than they are for, e.g., Typescript?
