Will electromagnetic weapons greatly replace the chemical energy propulsion weapon in the future war?

This is really hard to say, it depends on how technology develops.

Perhaps the most important thing is energy storage. Whether the battery, energy core or generator can achieve high enough energy density and provide a large amount of electricity, and at the same time, it is small enough for people/cars to carry around. If not, nothing can be said.

After that, energy weapons such as laser, plasma and particle acceleration can also be miniaturized. Whether to replace kinetic energy weapons, including electromagnetism, with energy weapons is another consideration.

Then there is reliability. Now chemical energy can be released by mechanical action, and the structure is simple and reliable. Electromagnetic weapons and energy weapons have complex structures and many electronic components, so the durability of the battlefield is in doubt. Can EMP electromagnetic pulse weapons be miniaturized? If an EMP is thrown out, all electromagnetic and energy weapons will be scrapped and can't be played.

There is also the possibility of producing deflection shields and the like after miniaturization of energy batteries, which will lead to a decline in the efficiency of kinetic energy weapons. Or an energy shield, etc. , leading to a decline in the efficiency of energy weapons, which in turn will affect the choice of which route weapons should take.
