With Project Loom getting closer to delivery, we will soon have a
world where even simple Java programs might use millions of threads.
This will, in effect, mean a world-wide multiplication on the number of
threads in Java programs by several magnitudes! This might seem like a
fantastic win for the Java eco-system, but we are forgetting the effects
on the real eco-system.
As you might or might not be aware of, the textile industry is one of
the heaviest polluter in the world. Adding billions upon billions of
new threads to this world seem like environmental arrogance.
I therefore propose we start Project Greenfield, which will research the
reintroduction of Green Threads, and study how much pesticide and
fertilizer use will rise due to Project Loom. Project Greenfields will
also develop prototypes to lower pesticide, fertilizer, and water use
for Java programs that need to create millions of threads.
Project Greenfields will deliver its first prototype in exactly one
years time, April 1, 2023. If this is successful, we can retarget the
project for the upcoming year, to look at the CO2 cost associated with
Java bean production.
