Thank God for them, otherwise we’d have no cars to get us to places we need to go. No planes to fly us where we want to go. Sail ships which would increase journey times by many, many factors. No plastics, synthetic textiles, pharmaceuticals. No fertilisers to grow the amount of food we need now. No trainers, waterproof clothing. No tarmac for our road surfaces etc etc etc.
Still we would have some things that we currently don’t have.
Regular and lengthy power cuts, people dieing of hyperthermia in the winter, no access to the internet, so no Not 606 (

)
a break-down in law and order, anarchy, being thrown out of our homes by the mob etc etc etc
