I think it is rather misleading to state "40 years of reasearch" the way you are doing it. It was only in the late 90s that there was theoretical reasons to believe quantum error correction is feasible. And your goalpost of logical gates completely disregards the enormous (more than 6 orders of magnitude) exponential progress in the lifetime of physical qubits (see sibling comments for references). We still need a couple more orders of magnitude before things work out at the "logical gate layer", but it is dishonest to disregard the progress up to now.
