Ask HN: How can I participate in the AI craze when I don't own a phone?

For a number of reasons, mostly privacy, I don't own a phone. But I noticed that pretty much all newer services require you to provide a phone number when you first sign up. While I sympathize with the idea of trying to make it harder for spammers and scammers, one implication of that is that I cannot sign up for most of these services. While there are internet services that offer throw away phone numbers that you could in theory use for the sign-up process, in practice you cannot use them when someone else already used the same phone number for their sign-up.

So, what to do?
