Perhaps the free version needs to go and make everyone pay for it, to increase profits. This might be unpopular at first, but a small fee for listening could work. This needs to coincide with the introduction of a HIFI tier. I pay £10.99 a month and it's on 12 or 13 hours a day sometimes. The AI DJ feature is great and has given me loads of music I wouldn't think of searching for. IF the HIFI tier turns up, I would gladly pay £19.99 a month to play all the tunes I play now, but in certified CD quality. Buying and storing these tunes on CD is not practical, or affordable. As I mentioned in another thread, the streaming amp sector can only grow and will kill CD and vinyl, eventually. Might take 5 to 10 years, but this technology is becoming more popular, with fantastic designs and features. Reliability will also improve and there will be streamers in portable devices and headphones very soon. Devices which don't spin, or have any moving parts will always last longer than those with wheels and motors etc. Look at the Rose RS520 and the Eversolo stuff. It's amazing kit you could never imagine 20 years ago.
There are limits to tech and what people want, if you look at phone technology it has basically stagnated over the last few years, sure there are some improvements but it mainly surrounds battery life and a greater reliance on Ai in the photo and video apps, people now are no longer changing their phones every time their contract runs out but hanging onto their phones for 4,5 or more years before changing.
In photography new cameras appear with a set of updated features fairly regularly but do they have any major technological advances, no. Since the introduction of mirrorless cameras the advance in technology has slowed dramatically, yes there are more pixels and they can take more pictures per second but otherwise tech improvements are not the huge steps they once were.
I'm not sure that the fantastic designs and features you mention are going to be the lifeblood of the streaming world, in many respects look at the mobile phone from its initial conception through to where it is today, initially huge leaps in technology from release to release, then slowly those innovations have declined and we are as mentioned before where we are today, what is there for the mobile phone of tomorrow?
I can already stream Apple Music through my phone to a pair of headphones and if the headphones are of a good quality I can enjoy excellent sound quality on my commute, in the gym, walking the dog etc etc., all linked from my phone to my headphones. True the connection isn't the highest quality but for a good portion of the population this will be more than sufficient, if I am sat on the commuter train as it clanks and creaks it way into the city having ultimate sound quality isn't my priority, offsetting the mediocrity of the journey is.
What will tomorrow bring? Well I think that in many cases it is already here, a large portion of the population can and already do stream music in their homes via Alexa or equivalent and for these people what they get is more than sufficient, a few will want to improve their lot and will step up but not maybe to a full system but just to a better lifestyle system, they won't want separate speakers or if they do they will need to be wireless as they won't want the wires trailing.
I am a fan of a one box system and have an aging Ruark R4 which I can use for Radio, CD, Streaming via my phone, Streaming my ripped CD's from a USB device, I can add a WiiM Mini or Pro to the R4 and have it connected to my home net work and get streaming access as well, this type of system is going to be big business in the years ahead., far more people will be interested in these rather than a separates set up.
Anyway that's my 10p of thoughts for today, off to play some spinning silvery discs for a couple of hours.
