In theory, probably?

It's a question of what's more practical to implement both in terms of energy and material resources to try and synthesize fuels from existing atmospheric gasses compared to electric vehicles and other routes

For some niche or remote applications, ICE engines will likely always exist just because hauling fuel to some locations will always be easier than electrifying

Finding alternative solutions for cars can't be the.only choice though. Like good investment into public transportation (trains, busses, etc.) can do as much if not more than any engine technology to reduce individuals impact
