Re: Boeing 737MAX Grounded Worldwide Q3 2019

It's puzzling that Boeing's proposed fix is to use multiple processors instead of a higher throughput processor. If 2 cores isn't enough, use 4 cores, or 6 cores, or 8 cores, or 10 cores. Multiple CPUs add overhead. For redundancy, a second x-core processor, rather than four, 2-core processors. 737...
