I'm a Software Engineer. Paint me incredulous.

This is not for a fix from scratch. This is what they have been working on since the Lionair crash.

The question is whether it will satisfy the regulators (worldwide not just the FAA now) now that the second accident has happened. It appears clear that any FMEA analysis done originally on the MCAS system has turned out to be inadequate. They'd really need to do another -- very careful, very thorough -- think through of this. Relying on pilots to turn off the system has proven [1] not to be sufficient for sensor failure cases that lead to already potentially confusing/overloading situations for the pilots.

And maybe they've done that.

[1] Ya know, assumin' everything we are all assuming' about the cause turns out to actually be the cause.
