They were never a test to evade bots to begim with, most capchas were used to train machine learning algorithms to train the bots on ! Just because it was manual labour google got it done for free , using this bullshit captcha thingy ! We sort of trained bots to read obsucre texts , and kinda did the labour for corps for free !
I heard Captcha was being used as training data for self-driving cars. Which probably explains why almost all of them ask you to identify cars, motorcycles, bridges, traffic lights, crosswalks etc.
