What is the motivation of Technicolor?

    Now I am reading on Technicolor. Unfotunately I am not clear yet what is the exact motivation of Technicolor? Please help me to clarify this. Thanks in advance.

    There is a QCD component to the W mass. Chiral symmetry breaking gives you a W mass term of perhaps 20 MeV.

    The idea of technicolor is to replicate QCD at a high enough scale so that this techni-QCD is responsible for all of the W mass. If you just scale up QCD, you get a scale for this new interaction in the TeV ballpark.

    But of course with this scaling to higher energies you are no longer able to explain why other particles stay light
