If it is MCAS pilot feels the pain, if the MCAS wins, situation is much worse.It will be OK if MCAS kicks only once and then awaits manual resetting. It is just unbelievable that nobody in the Boeing saw the big picture, clearly unprofessional design.
It will be bad software until it reports that it is reaching it's limits and why then hands back with a status report rather than a gong and a giggle
