#2I appreciated the 12:36 AM time in the video - most researchers I know seem to work best after 10 at night.

It's nice to see RISC-V getting adopted more and more. I wonder how long it will take until I will own a product with one or more RISC-V processors.

#5 Moving data around inside a computer means shoving it
through wires, which have inherent bandwidth
limitations and produce a lot of heat. Once that data
hits a network, however, it often runs across optical
hardware, which can send information long distances
at high bandwidth without needing a dedicated nuclear
reactor for power.

This paper uses the open-source Rocket-chip processor (https://github.com/ucb-bar/rocket-chip), which is the same processor being used (and modified) by lowRISC. So hopefully you can buy RISC-V in the not-to-distant future!

It's both increased bandwidth and lower energy. It'd be useless if it blew the thermal budget to achieve the higher bandwidth.

can you explain the mechanism for the bandwidth increase?
do the photovoltaics act as logic gates? doing calculations?
if the mechanism that is controlling the optics is electric:both transmitting and receiving; it would seem the throughput would be the same as pure electric
i understand fiber optic because light will travel a longer distance faster than an electric field propagated through wire, but these chips are built using atomic scale welding techniques(i)
