Emirates wasn't the first to mess up that way. Cases in Canada and the UK come to mind on both Boeing and Airbus. Systems like these have been proposed and made it to the prototype stage. One of the first systems was on the NASA 737 demonstrator, which invented the A320 for Airbus.
Typically called a Takeoff Performance Monitor (TOPM or TPMS). The problem with these systems is that the false warning rate, and subsequent high speed aborts, outweighs the benefits.
The real problem in Emirates and several other cases seems to be miscalculations or simple misentries. You can solve these by cross checking, uplinking performance data, and simple sanity checks on entered speeds, which both Boeing and Airbus haven't implemented. Often, TOPM still relies on aircraft GW and runway length, so you wouldn't be solving the problem.
A lesser factor is whether the engines are producing the commanded thrust, which is solved by the ACUTE system on the A380. There, percent thrust is calculated from a number of sensors and a model, and is used as your primary thrust setting measure. The landing performance monitor is somewhat easier to implement as well, which is showing up in the BTV system on the 380.
