Has Digital Audio Tech Plateaued - Is It Safe To Come Out Now?


I’ve been focused on analog for the last couple years with only an occasional glance toward anything digital.
 I could be mistaken but does it seem like the onslaught of technologically NEW digital hardware  and media has stalled? We’re seeing a move back to DAC technology that was prevalent in the 80’s, some folks say it sounds better (R2R)?
People have always questioned whether or not higher sampling rates actually improve things, beyond a certain point, so do we need more bits and higher frequency sampling beyond the current state-of-the-art?
We’re seeing some companies incorporate 1950’s tube technology into 2020 hardware to try to make it sound.....dare I say it - less digital?
Streaming seems to have matured to the point that it is what it is. The big streaming services have a foothold, and I’m not hearing of any real pending innovation. In fact I read somewhere that MQA is no better than CD playback quality, hence we may not even be as developed as we think we are.
Server tech seems to have peaked - sure, there’ll be more storage, moderately better power supplies, slightly improved interfaces etc, but is there anything revolutionary on the horizon now that we’ve moved beyond the Mac Mini / PC hardware?

 I’m not saying there won’t be a continuous stream of new hardware, new gadgets, but is there any expectation that something new is likely to advance us beyond where we’re at WRT sound quality?
Please note the question marks in the above, I’m not stating this is the way it is, I’m asking those of you who are closer to it for your thoughts on where it’s all at.

The point being - is it safe to crawl out from under my pile of moldy album covers from the 70’s and invest into current digital, without the fear of needing to retool in a year or two?
Thoughts?

@rooze No offense meant, but it feels like you already know the answer to your question. 

Your opening question implied lack of experience, but you've already made a real investment into the digital domain and as you are aware, the next step up will probably cost you all of the $10k.  I feel like there's a big hole between $2500 and $8,000 where many pieces across the spectrum all succeed in parallel, but slightly different, manners.  Who prefers what is totally dependent on system matching. 

And then above $10k, obviously you're into another league, but again one where price is likely to be very weakly correlated with performance above baseline.  By all accounts, the MSB Select II will sound wonderful for the rest of your life ( https://www.whatsbestforum.com/threads/msb-select-ii-arrival.23302/), but who knows about the many many options below that...
I think digital audio is going to be a lot like digital photography.
Currently digital audio is in the 12-15 mp range. Not bad, but when it gets to 24-45 mp, it is going to give vinyl a run for the money.
And, like digital photography, there will be filters available to mimic analog.

Yes, you need 45MP to get film resolution in best case but in low light film is useless.  I remember using 1000ASA film, gettin grain and dirty colors (400ASA was OK).  Today 10x that is still good.  Easy of use of digital photo is similar to digital music.  To me investing in digital only is way better than sharing money between two systems.  I have some breathtaking CDs showing that format does not impose limitations.

As with so many things in life (and audiophilia) there are two issues at play: quality and price. We all hope that at a given price point, as technology advances, quality formerly available only at a higher price point will become available. And at the upper end of what is for me stratospheric price—the current boundaries of “quality” will likely continue to advance. I think you are asking about the rate of change, and given current state at the higher end, it’s reasonable to believe that the state of art is advanced such that advances will be incremental. What I mean is that practically speaking we are at the stage that you will probably get more by paying more not by waiting longer.
