A lot of people are forecasting the death of the Internet as we know it. The financial incentives are too high and the barrier of entry is too low. If you can build bots that maybe only generate a fraction of a dollar per day (referring people to businesses, posting spam for elections, poisoning data collection/web crawlers), someone in a poor country will do it. Then, the bots themselves have value which creates a market for specialists in fake profile farming.

I'll go a step further and say this is not a problem but a boon to tech companies. Then they can sell you a "premium service" to a walled garden of only verified humans or bot-filtered content. The rest of the Internet will suck and nobody will have incentive to fix it.

I believe identity providers will become even more important in the future as a consequence and that there will be an arm race (hopefully) ending with most people providing them some kind of official id.
