What "role electons play" in antennas (not in fields)?

You should forgive Maxwell's ignorance and join us in the 21st century. Free electrons act as a "bucket brigade" for the coherent photons which make up the quantized fields/waves surrounding the antenna conductor. If Maxwell were alive today, he would have rewritten his works to correct his ignorant mistakes. Would you still be studying his obsolete works or his new corrected works?
