Water heater, 3/4" to 1/2" pipe
Hello. I am going to be installing a 40 gallon electric water heater, and it seems they are all 3/4" connections. The pipes in my house are 1/2". Will this be OK, using adapters?

I wouldn't think it would be an issue. I also have a 40 gallon water heater with 1/2" pipes throughout my house. My water heater was installed over 5 yrs ago and I've not had any issues.

That is a very common situation. Just use reduction fittings to make the connections you need.

Will it work yes, will you have far lower water flow and your going to think it's low water pressure, also yes.
A 3/4" pipe has almost twice the CFM of a 1/2" pipe.

I'm a painter not a plumber but while the outside of my elec water heater can get warm, it never gets hot. It's been close to 45 yrs since I've had a gas water heater but I would think there would be less danger because there is no potential for gas build up.

Depends on how you look at it. Certainly not the electrical connections themselves. But heat dissipation should be considered. The pipes exiting the tank should never be so hot as to transfer enough heat to a piece of wood or wall as to allow for combustion. You could add insulation to the pipes.
A gas fired tank is a whole other story. You must allow for combustion air if not coming from outside. Allow for flue pipe exhaust. And you must keep any combustible at least 12" away from flue. You also want free flowing air space around the tank.
