Well, if not the Seers, then at least some nefarious group of mages has been at work on mathematics, to the eternal pain and misery of mathematicians everywhere.

I have a textbook which, for no reason at all, decides that it's super cool to use a regular dot for multiplication instead of the middle dot (·), so a.b instead of a·b, so you end up getting stuff like 3.4 which might be a single number or a product of two numbers. You can't tell unless you look at the context.
And it also decides that it's really fun to write functions such as f(x) like xf instead, like you were multiplying x and f rather than taking f of x. I do know this leads to some minor simplifications later on, but it also leads to a lot of the opposite.
I totally gave up on that book after that.
I agree clarity and not scaring away young people is super important, which is exactly why tau should be used instead.

Throwing out all the good that tau does because teachers fail at teaching division to kids is totally missing the problem.
