Maybe it's been stated already by someone else here but I really hope that CO2 pricing on the major Cloud platforms will help with this.
It boils down to resources used (like energy) and waste/CO2 generated.
Software/System Developers using 'good enough' stacks/solutions are externalising costs for their own benefit.
Making those externalities transparent will drive alot of the transformation needed.
Btw: what's the best source for these kind of one of a kind, contra-intuitive algos and datastructures? Be it online, be it books...
BWT can't be the only one, right?
