Wouldn't this apply equally to AIs?

The brain shows an ability to repair itself and grow, an upload should also
be able to.

I would think it more likely that uploads are either illegal or not
recognised by the law as alive.

Fair enough, but there are many technologies that are more dominant then
people thought as well.

It would appear that we have reached the limits of what it is possible to
achieve with computer technology, although one should be careful with such
statements, as they tend to sound pretty silly in 5 years.
