Only if ASIC resistance wasn't a fake concept and could actually be implemented.
asic resistance does not lower electric usage. it just lowers hashrate/difficulty
those on asic resistant algo's just end up setting up GPU farms
which have high electric usage for low hashrate output (inefficiency)
EG 1x s19 asic = 3.25kwh for 110,000Ghash
16x GPU rack = 3.25kwh for 1Ghash
miners have to follow the rules core developers set out.(singular reference client point of failure weakness of bitcoin*)
users follow the rules BUT if the rules changed overnight(mandated/contentious fork). they follow the network that is most accepted by majority of exchanges/merchants/services(so that people can spend coins with known services)
something to not be afraid of this second but be aware of(for research/learning and matter of fact knowledge of risk) a possibility.
another "mandatory upgrade" could occur (blockstream +NYA tactics) but next time via regulatory push, involving mandated activation code that signals a changeover to a non-PoW mining algo
whereby (scenario to be aware of)
all the main licenced/regulated exchanges/services/merchants have to regulatory comply to agree to only accept non PoW coins, (call that the NY agreement comparable)
where they also push the core devs to code it(call it the Blockstream push comparable*)
take a few moments to think of the ramifications of the 2017 tactics used to mandate a feature upgrade, being used again, but this time by regulators pushing devs and exchanges to collude and push for another upgrade.
just so that you can be aware of possibilities
if a financial portfolio group DCG managed to pull it off in 2017. regulators can too
*dont turn this into a social drama debate about insults, taking sides, defending brands or pointing finger or trying to rewrite history depending on loyalty camps.
just use the hard data,code, facts of history of the event that occurred. to think about how it can be used again in the future against bitcoiners.
for people to watch out and prevent the risks, people need to be aware of the risks. dont shy away from being risk aware.
