Untrained testers will behave like monkeys with typewriters and sometimes find bugs. The quality of the bugs will be questionable. Professional tester will actually consider what can go wrong (like using boundary value analysis) and catch the issues where they are harder to track down. Also the tester will document the process (use case, testing scenario, test results) in an accountable manner and can save you from being sued at one point.

Found KDE complicated? You should go back to an etch-a-sketch.. Yikes, is this the quality of people using Linux these days?

Wake me up when that Rube Goldberg gadget they designed actually works.

The Kfir was at best a Mirage clone and was built to go around various arm embargoes at that time. It was also built based on secretly handed-over Dassault plans and equipment after De Gaulle publicly created an embargo. Finally Israeli got a lot of modern weapons from US and currently mostly rely on US-made planes - which wasn't the case way back then, they were mainly supplied by French. In any case it is alleged that many of the blocked aircraft ended up in Israel in crates.

Please elaborate on how the secrets of an anti-ship missile results in total defeat of the air force?

It is also the plane US Air Force most wants to cancel. It's not fast, it's ugly and it does its job extremely well. That's why every decade some idiot in USAF pops up and demands a fast jet tank killer. F-16 was the favourite one a couple of decades ago, now I hear F-35 will be the one. Meanwhile, the reality has its own rules.

They share the glory of launching humans into space with China at the moment. On the other hand, Russians don't have a good track record of creating a brand new design for a while. Kliper is dead, their shuttle did one flight and they haven't managed to design a single human-rated spacecraft since Soyuz and that was in 1960s. Sad fact: Both Russia and Western countries have stagnated.

Because history has shown again and again that humans are very bad at judging risk.

Sir Paul has a lot to answer. To fill a selected bunch's wallets with cash, a lot of other things are just disappearing. All of the out of print books will be gone, thrown away, slowly ending up in the £4 per 5 bin and so on. And all those old 50s LPs, getting broken one by one in charity shops.

Not spontaneous? Obviously it's a random mutation causing a difference in biology was selected by environmental pressure. Evolution works.
