Why did the Boeing 737 MAX wait two years to crash twice in such a short time from each other?

Is it me or were some of these aircraft flying with no issues for TWO whole years before the crashes? The media didnt even bother to mention or even look into this, am I right?

Were there instances of uncontrolled dives (while at higher altitudes) that occurred before the crashes? Didn't pilots have a chance to recover, report the problem? And it was not traced to a cause?https://www.thedailybeast.com/before-fatal-lion-air-crash-boeings-new-jet-hit-problem-in-tests
Read this from a long article: "The company committed to improving the quality and timeliness of information it provides to the FAA. But in the case of the 737 Max, the FAA said, it took Boeing more than a year to notify it about a software problem that disabled a crucial warning light connected to the automated system at the center of the tragedies." https://www.washingtonpost.com/local/trafficandcommuting/long-before-the-max-disasters-boeing-had-a-history-of-failing-to-fix-safety-problems/2019/06/26/b4f5f720-86ee-11e9-a870-b9c411dc4312_story.html

Boeing has said that the crashes are the result of a software update it made and downloaded to 737 MAX planes just before the crashes started. It did that when it advised all airlines to ground the 737 MAX until the problem could be fixed.

Media coverage of anything related to aircraft safety is not reliable. Sensationalism sells, facts don't. Ignore all the hype, and try for transcripts of hearings and copies of actual documents. You won't recognize the indecent.

Simple probability statistics. Because when the first plane entered service, it was alone.
There were only 74 in service at the end of 2017.
But 330 by the end of 2018.
If the rate of crash is one airplane per 165 per year, then there should have been none in 2017, and two in 2018.
Boeing was ramping production to 52 per month when the plane was grounded. At that rate, there would have been over 600 delivered per year, with 4 of those statistically crashing before reaching one year after delivery.

AoA (Angle of Attack) vanes don't fail that often.
Both of these crashes required an AoA failure to occur during a flight regime when MCAS was tasked to correct a "nose high" indication.

the specific conditions required to result in a crash were not met, genius.

Since the aircraft (like guns) are just machines, I don't think they "waited" to crash. They crashed because the autopilot locked out human control inputs after it misinterpreted it's attitude (flight) due to localized weather patterns. They were grounded because the autopilot can't tell up from down if the wind changes direction and won't let the pilot take over.

You are insinuating that the jets actually planned this?

Some software takes a while to start causing problems in this case it seams it was a new software
update which had faults.
