I'm a Realtor, but I'm not here to turn this into a pissing match - if you believe that representation doesn't benefit you, then don't use a Realtor. In the same way, if you believe you can represent yourself successfully in court don't use a lawyer or if you can adequately assess your financial future, don't use a financial advisor. Expertise exists for a reason - because I can tell you a lot about water rights, land use, zoning, negotiations, market and pricing, and I can connect you with other professionals to meet your needs. Many people find those professional services to be worth their time and money.

All that said - yes, I think we will see changes to the cost (commissions et al) of real estate services. But when I hear people talk about "normal" real estate transactions or comments like "you don't need an agent for residential" I know this person is either very new to real estate or very experienced. The newbie doesn't know what they don't know, and the experienced person likely has sufficient knowledge that they will only bring in an agent to supplement that knowledge. The majority of people do not transact enough real estate such that they may think they know more than they do.
