I think this is underselling it a bit. If you'd told this to the IBM engineers at the time I think they would have taken great interest in how the performance was achieved.
Biology had a lot of time, attempts and pressure to make this work but even the most optimized lines (something like a magpie) need more complexity (almost a billion neurons) to get a fraction of superhuman intelligence.
Results with small artificial neural nets are very limited so far, too.
