Since when are captchas a bigger issue than spam bots and fraud users?
and yes i also think that those tasks are actually helping our society. Adding models for self driving cars, for security/emergency breaking systems etc. So whats the issue?
If I had to guess:

My experience is that it can be a real hurdle.
Sometimes reCaptcha forces me to complete 2 or 3 captchas (or more), some of them with an annoying artificial delay when loading new images. It seems to be worse when using a VPN or a browser like Firefox (or some privacy extension) that blocks Google tracking.
I understand why people use reCaptcha and that it works well for some users, but it can be a pain in the butt if you don't use Chrome, aren't logged in to your Google account, or if other devices in the network did something that Google doesn't like. I sometimes get captchas on my phone when using mobile data (on a major provider here in the UK) and Google search because of "unusual traffic from your computer network"...
