I believe the point the parent is trying to make is that when you spend the time to learn Visual Studio, vim, etc. you can transfer that knowledge to multiple languages. With Pharo those tools are limited to, well, Pharo.

The benefits of learning a particular tool are essentially proportional to how often you use that tool. The greater flexibility of other tools such as vim means that the cost of learning it can be amortized over essentially as many projects as you wish. The costs for learning Pharo tooling are only spread over as many Pharo projects you do. If you don't believe you'll be doing all that much in Pharo, it makes it a fairly daunting proposition to invest that time.
