If new developing is happening, as it was in this case, that doesn't really matter. This problem was amplified by maintaining old technology, not mitigated by it.
I don’t agree. The failure(s) weren’t in the old stuff, they were in the poor and ultimately unsafe cover-up (for lack of a better word) of the new.
The CG change from the new engines specifically, being masked by new software, MCAS. The only old part culpable is the legacy 737 limit of 2 AoA sensors (with only 1 used for MCAS input (a new thing)).
If they had used the new technology available in other jets -- the pilots wouldn't have been sifting through paper manuals to find the problem. The would have an actual display.
And if they weren't trying so hard to purposely avoid modernizing the cockpit, the issue would have been avoided altogether.
