How to build an INVINCIBLE machine?

Is it possible to build an indestructible machine?

Mr. John explores the difficulties with creating something invincible and what the logical solutions would be. It may seem like a useless thought experiment, but it also has some important implications for our world as we know it.

Can you figure out why this matters? And can you figure out a different solution?

P.S. this isn't the end of the indestructible machine. I will try to post the advanced guide at some point (can't guarantee it will include animation. The art may be terrible, but it still took a lot of work).
