Luckily in some parts of the world engineer still means something by law, even in informatics, and one is not allowed to use it just because they went through a six weeks programming bootcamp.

Engineering implies scientific rigour and high intellect. So, no wonder software developers, usually a derided and mistreated collective, just love being called engineer...

Engineering (as in PEng in the US, but my jurisdiction just calls it Engineer) also implies liability, and a risk of losing your license if you fuck up.
