Simply saying 'fundamentals' allows one to nullify things they don't understand, like owning the rights to one of the biggest duopolies (x86 that without one becomes a monopoly).
The issue with tech, much like math, is that it often takes a while to figure out all the potential, case in point GPGPUs and Deep Learning revolution. The tech, the ideas, the internal code/models, the people (Jim Keller in AMD, and TSLA) are all catalysts that can't be quantified in the same way as traditional 'fundamentals' are treated.
