If institutions spent on solutions for Linux, instead of Windows, all these things would be available and optimised for schools long ago. Training the next generation to be Windows users means just more ads, more illegal loss of privacy and more bugs and disastrous usability in perpetuum. We are seeing more institutions breaking the cycle. Getting together with other institutions and starting the process of moving over. Not taking the lazy option to follow the status quo.

The interactive approach should be just as future proof. Programmatic interfaces are not really suitable for many designers. Who work more intuitively with direct visual interaction. I couldn’t imagine doing really complex stuff programmatically.

The primitives are parameric. I’d assume ACIS solids are too? You can try it out yourself by following one of those links.

Look out for any Linux dip in figures, as some people give up trying to use Linux, and move away again. If they hit a tricky problem, and go online for help, some will just scare them away with an over techy response. And they will share their horror story, keeping more people away from Linux.
