A recent report by Startupbootcamp and PwC points out that startup trends in 2016 moved towards artificial intelligence (AI) and machine learning companies compared to blockchain; the data shows that 16% of applications to Startupbootcamp are from artificial intelligence and machine learning companies, whereas blockchain applications account for only 6%; blockchain was certainly a bigger buzzword in 2016 but one reason that AI and machine learning has more startups is because companies like Google, Facebook and Amazon have made significant investments in the technology; additionally, the report points out that as blockchain becomes more industrialized more startups will use the technology instead of being a blockchain startup.
