Depends on the community. In Lisp communities, for example, it's very much a hot take. Which is a shame, because I'd love a statically typed Lisp-like language.
Tabs are designed for tabulation (hence the name), not indentation. The side effect is that a tab's length changes based on its position in a line, which is terrible for programming. If you use tabs in the Python REPL, it looks like this:
>>> def frobnicate_all(arr):
>>> for item in arr:
>>> frobnicate(item)
C++ makes programming look way harder than it actually is.
