While it isn't exactly scientific adding together lines in research, so while 40% say AI (the largest sample) will be the technology of 2018, if you add in the people talking about chatbots then you get to three quarters.
Where as account based marketing does not even move the needle. Maybe as this is now Business as Usual? Blockchain and cryptocurrencies, while we have all watched the Bitcoin growth over the year, I'm not sure we can make the jump to practical marketing uses. If I'm wrong, please write and tell me.
As you can see, AI is by far in the lead with almost 40% of marketers saying artificial intelligence, machine learning, or deep learning will be the most transformative technology for marketers in the coming year. Add to that bots/chatbots and voice search and assistants, which rely on various levels of AI for their intelligence, and you hit almost three quarters of marketers.
