Supersymmetry people always argue that it can help to unify the coupling constants of the strong weak and electromagnetic interactions; they come together to a single value at 10^16 GeV. That is an argument for supersymmetry, they claim.
But wait. Why should the coupling constant reach a single value? After all, the coupling constants of the electromagnetic and the weak interaction do not reach the same value, and still the two interactions unify.
So we do not need the same coupling constant value for unification? Agreed. But then we do not have an argument for supersymmetry any more? Agreed. But then supersymmetry people are telling nonsense? Agreed. As a check for the last conclusion, ask your favorite supersymmetry expert the following question. At energies higher than 10^16 GeV, the three coupling constants separate again; are the interactions not unified any more at higher energies?
You will get answers like: "We do not know what happens there." So the supersymmetry people who propagate the argument that unification requires a single coupling constant are people who tell us that we know what happens at 10^16 GeV, or
10000000000000000 eV,
but we do not know what happens at 10^16 GeV plus 1 eV, or
10000000000000001 eV.
These people can calculate integrals in fermionic space (which does not exist) but are unable of simple logic (which does exist). Supersymmetry "experts" are really hilarious.
