At the end of 19th century a famous Polish mechanician wrote a paper that flight of a body heavier than air was impossible...
In early 1970. another famous professor asked about perspectives for the Finite Element Method said, that the method led to large sets of equations which were intreatable. So the method would not be useful. Since 1990 with the exponential grow of computational powers of computers the FEM became the main numerical method in mechanics.
When I first get in touch with Spectrum PC with 48kB memory back in late 1980. I would never imagine that in a couple of years I would deal with documents of hundreds of kB and in a next couple of years a mere .jpg file from my digital camera will have 5-7MB and I would owe a rather small portable disk of 500GB...
Well, Ian, I am afraid it is indeed a question of short time... In my opinion the main point is, how we modellers take these news. Will we still be decided to build models from real parts or rather design them in virtual reality and then, print them... Or even not so! Will it not be like with photos? There were times were photos were hardware, I mean - prints in albums. Now the majority of people I speak to about it do not order prints from the files. They are satisfied with presentation in the screen. Me, I still order prints, a few days ago I put into album over 700 prints from my recent travelling.
But how will it be with models???
