I was working for a place that was the market leader in a certain niche of simulation software. Their simulation was about 10x more efficient than their competitors. However, that version of the software is strictly off limits for the public, and made a version which they sold with a sleep statement so that it was only 1.1x faster than the next best solution. That way they could remain market leaders any time the competitors released a better version. Even though many systems rely on growing simulations to simulate bigger scenarios that could help save lives.
Just an example of capitalism impeding progress.
