Only if you include the learning time and the lost productivity in that cost. In reality it will never happen. Think of it as switching every keyboard in the company for a Dworak version. That will not meaningfully affect your average programmer's productivity, as their typing speed gained from a faster layout gives only diminishing results. Dworak only makes sense for a programmer that really benefits from >100 words per minute, and most really don't. The bottleneck it the programmer, not the input. The same goes for VR, unless you have a special case as I have mentioned before. Let's say you type 300 lines of 80 characters of bug-free(!) code per working day of 8 hours. That is an pessimistic estimate( for my theory ), average is much lower. Let's assume the average typing speed is 60 words per minute. That gives you 83% of the time not spent typing(!). Doubling the speed to a very fast of 120 wpm, only gives you 92%.
