So, Artyom says that storage and element access alone is insufficient to
warrant the existence of a library. Alfredo says something opposite.
Alfredo, what would help here is if you demonstrated that your library has
users, and have the users say why they chose it, given that they have to
get the algorithms from elsewhere. Maybe you are such a user?

The rest of my post is "academic", as I do not have experience in the field.

Having only the storage and access abstraction would be preferred over a
framework, if for your particular use case you have to employ two domains,
like image-processing and generic AI/ML, and you want two sets of
algorithms applied to the very same data. Then there may be no single
framework that satisfies your need, and you may need to make two frameworks
interoperate.

Next, the analogy to STL alone is not good enough, I think. It is on you to
demonstrate that the idea of generic programming also applies to *real
life* usages of big multidimensional arrays. STL itself has been criticised
that because it is generic, it cannot be optimized for particular types. (

In the context of big multi-dimensional arrays, we are talking about heavy
computations. And maybe the data structures not optimized for specific use
cases are simply disqualified from the outset.

Please, treat it as a hint on how to communicate your ideas to people in
this forum, in order to convince them.
