There is a small market for layered fonts, which have been available for 25+ years. So, not much market-driven demand for huge change there.
Colour will never be the new bold. When one uses colour for contrast, one usually bumps up the weight. That’s because colouring type doesn’t make it bigger, which bolding does, and also makes it less clearly defined. Color can produce meaningful contrast, but for type it is always weaker than boldness.
On the other hand, apparently my house is “powered by Rogers” (internet service provider), so anything goes.
Indeed, he was adopting a style of design he felt was appropriate to the content. It does look a bit forced, and it’s hard to know whether there is an element of parody or not, as few British or American designers of the time really “got” European modernism.
I’m not quite so pessimistic. Having worked as an art director with some appreciation for type, I would often find it very difficult to find the typeface that was just right for a job. And that is why I would licence a new one. Also, one comes to realize that the original is better than the clones, and some typefaces just are quite unique. Others, new, just seem right for the time.
Also, bear in mind that many designers don’t like to cheat, and many work for businesses that play it straight with properly licensed software, because they are concerned about the legal ramifications of piracy, as well as bug issues.
