I think that as the world is moving towards sustainability and electrification, all feeder series to Formula 1 should be electrified after 2039, and Formula One should stay hybrid. What do you think?

I personally think it should happen ,this would prevent Formula one from going electric .And that is why the fun and thrill of Formula one engines and the sound etc ,indeed everything for which F1 is loved would stick as it is .Moreover the current performance figures of Formula E cars justify there use for feeder series .The power is approaching 350 horsepower and the battery levels are enough for a small 30 + laps race . As a plus , as Antonio Giovinazzi said that driving Formula e was like driving F1 car in rain , it would be a good simulation and practice work for future F1 drivers . And plus this would also be like 3 racing series going electric (F2,F3,F4) ,So there will be great environmental benefits ,if we agree upon recycling batteries and stuff . This would also give a chance to every manufacturer who is manufacturing F4 cars etc regionally ,to have a chance to develop advanced electric powertraind for future electric cars .
