Dan,
From reading your posts, it sounds like you’re a “glass half empty” kind of guy.
Following your logic, the post production industry is going to wither and die tomorrow. There will be no more high quality work done anywhere, and if you’re over 21, you’re too old to work in this business.
I see a different future!
The tools are ever changing. I didn’t start out my career editing on a Mac, and I’d bet when all is said and done, I’ll be using something else years from now. So what! Who knows what kind of developments are brewing in Cupertino or elsewhere. I’d rather contemplate the challenges of editing my next show, than worry about what kind of computer I’ll be using.
