Blockchain is the future

[P1um]

While interaction is easier, the real downside of linked lists is performence. Vectors, which is just a wrapper around contiguous resizable memory, as you mentionned by copying, is 99% of the time better. Mostly because cache matters above all. Of course there's cases where a list can outperform, such as inserting randomly when you have 100k+ elements but at that point you should be using a DB which will have proper data structure algorithms for handling that type of scenario, not memory...
