We know. Change is hard. And change when it comes to technology is especially hard. If you’ve spent lots of money on a system, or are just comfortable doing what you’ve always done, the idea of using new technology or a new system may seem scary.
Maybe if you have a local monopoly or market power, like the agency discussed in the article linked above, you can avoid change.
But for the vast majority, reality has a way of forcing your hand. Clients, opposing counsel, and even now courts and bar associations require modern technology. If you don’t adapt, your practice will die.
