He said today's aircraft design and training programmes placed emphasis on co-operation between crew members unlike "in the old days when all the decisions were made by the captain".
Seems to me that this arrangement will place more, not less, responsibility on the shoulders of the captain than ever before. A pilot and a gear monitor don't a crew make. Right back to the old days of single pilot captain and seat filler/chief bottle washer. Except that these days, cappy will probably be required by feel-good company policy to pretend that the gear monitor has an opinion worth hearing. I hope they are up for the extra work.
So be it!
