We had 35 participants at our summer school a few weeks ago testing this on their laptops. Turns out a Macbook M4 pro is almost as fast as a 10GB slice of an A100. From the school, here is a 1-hour reconstruction. (Data took a few seconds to record at the school in a crowded scope room)

This has been going for a while. When I worked at Lumon, erm Lucent Technologies in the late 90’s this similarity was also noted, but that is was also inflamed. Still an improvement on the previous deathstar logo

Updated for this years list - maybe NatureSpringer will have to merge with Elsevier to keep up with mdpi
