Yes,
bd is doomed, just like 3d-tv, cd, dvd, etc.
But it's not dead and it's getting more popular all the time.
Do you also think that because you are doomed to die in some day, you shouldn't enjoy your life before you die?![]()
Why choose to die when you can be immortal?
Let's take your lifespan analogy a bit further. Let's say, heaven forbid, a doctor came to you and said you had a terminal disease. However, he also tells you that you have two options. First, you could do nothing and die in a few years. The alternative: take medication with minor drawbacks but keeps improving all the time and may let you live indefinitely with a better quality of life than you've ever had. So, which would you choose?
