I was there that 2019 Visalia evening at WB6RSE's Topband dinner and George's presentation on concurrent CW / FT8 on 160m blew me away too.

At the most recent Visalia in 2019 (and later at Dayton, I think), George presented two feats of engineering excellence that blew me away. First, his "Radio In A Box" has the potential to revolutionize DXpeditioning to islands, drastically reducing their cost, the number of hams needed, man-hours spent on the island, and the resulting impact on the island's natural state. All of this has the potential to make it far easier to obtain permissions from authorities.

Second, his observations that during DXpeditions, topband openings tend to occur on one night out of a couple of weeks, and that since CW and FT8 are the dominant modes for weak signal work, both need to active whenever there is the likelihood of propagation (that is, between the daylight sides of the terminator), led him to devise a system to achieve that.

Both of these achievements are described on the qrz page for C6AGU. If you've missed them up to now, by all means check it out!
