Too bad the author did not mention Lightning Network. The issue covered in this article is one of the reasons LN was chosen as the scaling solution instead of the block size increase (i.e. bcash).
Second, the lighting network has been promised for multiple years. There are warnings right now that no one should use it for real money because there are multiple very real security and design problems with it.
If block size limits don't change, it will take thousands of transactions on each lightning channel to make transactions as cheap as they already are on bitcoin cash (and many other crypto currencies). Changing the block size is technically trivial, but the core team still thinks they can censor, lie and corrupt their way to making money off of suffocating bitcoin.
It should be obvious to anyone with a drop of critical thinking that 1MB blocks every 10 minutes is absurd. CPU, bandwidth and memory are all trivial even when taking the throughput up by 100x
