Please care to explain why a physical media is obsolete? please enlighten me
1. Obsolescence as a mean of additional storage
In the past physical media was needed as an extension of the available storage.
Consoles just didn't have enough internal storage to hold games, so they read them directly from physical media.
This has changed considerably in modern times, where consoles not only have enough internal storage, but they also very often copy the games into it to make them run faster.
Games sold on physical media doubling as additional storage is obsolete due to this.
2. Obsolescence due to the current continuous game development model
In the past games were often developed and released, and that was it, the games didn't change further.
Nowadays it is quite common to release patches frequently, adding plenty of content be it by free updated or by purchased DLCs.
This has been progressively phasing out the concept of a static physical media as a relevant mean to sell a game.
Games sold on physical media are also obsolete due to the continuous development model
3. Obsolescence due to manufacturing costs
The cost of manufacturing a physical game and putting it in stores is to be considered.
In the one hand you have to pay for the production (that may not be so costly), but you also have to give the share to the shop that is selling it.
The need for reduction of those costs is making physical media obsolete.
4. Obsolescence due to logistics
When you produce physical media you never know how much you will sell (you try to predict it nonetheless).
This could result in situations of overproduction (like Atari's ET) or subproduction (like e.g. the recent case with Octopath Traveler, but I think that is a publicity stunt as my local Saturn store is full of physical copies of that game).
In order to avoid this logistics problem you can just publish the game in your digital store, copies are automatically "produced" as needed.
Also you don't have to pay the additional cost of sharing the profits with the shop owner as in when you sell physical media.
The necessity to avoid logistic problems and maximize profits is making physical media obsolete.
5. Obsolescence due to wide availability of high speed internet
In the past the lack of wide availability of high speed internet was a cause against digital downloads.
The situation has changed drastically in the last ten years, with high speed internet available almost anywhere.
The availability of high speed internet is making physical media obsolete.
6. There are many other reasons
Like for example streaming services that depend on NOT using physical media.
Many people has been exposed to many streaming services and subscription plans and their advantages and due to this they are now familiar with them.
This familiarity and will to use such services is also making physical media obsolete.
