Can you prove that computers wouldn't have existed anyways or in even a better form than they currently do?
No-one can prove a negative.
Then you probably shouldn't make an assertion that you can't back up.
I made no false assertion.
The issue here is whether or not society is entitled to reward research. Whether its investments in technology or medicine or even safe cars, society is entitled to enable that research and it uses intellectual property as the mechanism to do so. You and Frederic seem to think you have the right to dictate to the rest of society whether or not it has that right. You don't.
