Partly because of the changing pace of technology. A watch company could be pretty sure 100 years ago that watches would still be around in 20 years, sure the technology might need to be updated but not dramatically. You think anyone will even use Heroku in 5 years? There is a new language and technology every month now that gets hype, it's unlikely something like this will continue to grow for the long term.
I'm sorry but that's a bullshit notion. Why is anyone still using PHP today? or Java? Just cause something new comes out, it doesn't automatically displace the old. I think paperback's are more likely to go away before the last rails app is written.
Agreed. Also, why does a company have to be tied to one bit of technology?
We hear a lot that being a good programmer/designer/etc. isn't language-specific but that it is a skill-set that transcends technical knowledge. Why isn't this the same for companies and products?
