If a web page gives an error, then users try to ignore it, try
with another browser and worst case just try again next day - and
nobody is really surprised. If airplane control software has an
error that cause a crash and kill hundreds of people, then it
makes world wide headlines.

I don't think the word *just* in "just an attempt to add static
typing" is a fair description.

It does add optional static typing, but that enables a lot
of things that impact how code is written: different way
to do OO, generics, enum etc.. It is a significant change.
