No, matter doesn't become energy till it does something. The idea that there's something called energy apart from matter is woo.
Um, please do not call woo on me, I say this as do other people in the SMT forum all the time. And the big smarties of physics do not correct us.
Matter is energy, energy is matter, 'matter' and energy are interchange-able concept.
In fact there is no wave particle duality , all matter is waves all the time.
I do not know why you insist on this semantic distinction between matter and energy.
If you wish we can take it to SMT and discuss it there.
So what are photons and other bosons?
The second part of your post is you moving the goal posts.
