But if you did a lot of things you might know what does not work and why. Similar to science articles, nobody talks enough about "X technology does not work for Y domain", so a lot of people try to "reinvent the wheel" only to realize "X does not work for Y". Occasionally there is a surprise (because of some technology advancement) but being old definitely gives you more insight in what can go wrong.
