But ultimately, most Rabbis know that these reasons have mainly been brought up to avoid making those "holy days" look like other days by allowing the use of computers, microwaves and so on, so it's not just going to go. Every practicing Jew has thought about it. Many hope our Rabbis change their mind one day, seeing how hard life without electricity has/will become and how plausible solutions may exist.
