Why is it really hard to find someone nowadays?

I never found someone I dated for a long time. Longest was 2 months and it wasn’t really serious anyway. I met sometime recently and figured he’s not worth my time as well. He Texted saying he wanted to make plans but that he has covid. It has been 2 weeks and he hasn’t texted again. I do not know if it is just me but I found it Hard to find somebody that shows real interest. Any thoughts on this?
