One day, you may reach the further realisation that those same very
smart people *do* understand tabs, and *do* know how to use them — and
nevertheless choose not to put them in source code, for good reasons.

The makefile syntax is one of the excellent examples of why it's a
terrible idea to use tab characters in source code. It's also an
excellent example of how a poor design decision (a line beginning with
U+0020 SPACE is semantically different from a line beginning with U+0009
CHARACTER TABULATION) can be irrevocable – the syntax can't be changed
now, without breaking compatibility for countless makefiles out there
already – and cause endless confusion and wasted effort dealing with it.

Using a mature, well-customised, language-agnostic programmer's editor
does make it much better: Vim and Emacs can both seamlessly handle “tabs
are forbidden by default” as a configuration choice, along with “tabs
are necessary in make files, using spaces in the wrong place is an
error” at the same time.

Hooray! Welcome to the light :-)
