BEGINNING: I think it's true because some computers now have facial scan recognition, but they cost an arm and a leg to buy but i don't think its worth it to buy a computer that cost an arm and a leg because if something goes wrong with the computer their will be no refunds but there should be refunds because they could probably sell u a broken or damaged computer.

Next: do think it would be a good idea to make a computer that's u can only access with your face because nowadays people tend to steal stuff that doesn't belong to them like for example I had a friend who tried to steal my headphones one day but I had officered force her to give them back but when she gave them back they were broke.

Conclusion: I think that Mona Lisa probably was a hard picture to face scan because there were so many different copies of the original painting but I'm pretty sure the real painting is in a museum heavily guarded by people with heavy artillery and grenades and army men with truck but in conclusion if you're a great painter do your best because one day u might a famous painter like Leonardo da Vinci or better
