Ah, ok thanks. SO the only way to fix it is by deploying new miners.
No that wouldn't actually fix it. There is a limit to how many transactions can be processed regardless of how many miners are running. Adding more miners doesn't actually increase capacity just the difficulty.
If you deploy more miners the average difficult to mine each block will increase (as for the bitcoin rules) so you are back to square one.
Yup, I expected this.
The way to fix this is increasing the size of the blocks, which is trivial from a technical standpoint, but it has some implications that the current majority of miners are not willing to accept.
