Absolutely. It's unclear if the max crashes could have been mittigated by better training (and that Boeing did not really make the MCAS addition/changes as a big change is a huge issue) though by the 2nd crash the crew were seemingly aware of the issue but still unable to get out of it.
I guess my point when it comes specifically to the 320 series early issues is that they involved, as I understand it, in some instances, issues with the computer control systems (which aain in the 80's were very new to aviation and a brand new philisophy) and there were software issues that had to be resolved. Same with MCAS which essentially has been a software fix (I know it is way more complex than that involving other parts from 3rd party suppliers and all the rest - eg the Angle of Attack sensors etc).
I don't want any reader to think I am trying to defend what has gone on with the MAX. I'm not. It's such an example of all the wrong things that have gone on in the name of engineering and safety being placed second to costs and "get it done" mantra - from a company renowned for such a focus on safety over the years (look at the 777 program as example). That the seemingly sloppy practices with the 787's built in South Carolina (tools being left in compartments etc) and other issues are very serious too and probably related to a cultural issue. I do not wish to defend any of this, because you can't and it would be ridiculous to attempt it. I bloody well hope the company has learned a very VERY huge lesson (tragically for so many) and manages to rebuild the original culture and focus that made the company so well respected for decades.
(full disclosure: I was once offered a job at Boeing in Seattle so I do have a soft spot for them, but that was 26 years ago and a lot has changed).
Back to what I was trying to get at is that the 320 series had some initial problems with systems that were resolved and it's now one of the safest fleets out there. the MAX, with all the scrutiny and awareness I personally feel is going to be just as safe going forward. It doesn't dismiss the past in any way, but just like I am more than happy to get on an A320, I would get on a Max. I also believe in unicorns and rainbows and "simpler and fairer"
