I did it on purpose. There are advantages and disadvantages to using many different technologies. More technologies mean more options and strategies. However, the amount of research required to advance a large number of sciences will slow down the overall progression of the race. Many advanced techs require a large "entry fee" of research points to even begin that area of study.

For example, a species researching both Crystaline Manufacturing and Mutation Control would require twice as much research time as a species devoted entirely to Solid Energy Studies. The pros and cons are notable for both sides.
