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"...
