Not at all, originally template metaprogramming was discovered by accident.

Cannot recall any longer if the original article on the matter appeared on The C/C++ Users Journal or Dr. Dobbs.

Eventually it started to get abused and the Turing completeness has been discovered.

Since C++11, the approach to a more sane way to do metaprogramming with templates has been improving.

Instead of tag dispatch, ADL and SFINAE, we can make use of concepts, if constexpr/eval/init, type traits, and eventually reflection, instead of the old clunky ways.
