I'm cautiously optimistic that immunity will happen. A dear friend who is working on his MS degree with a focus on viruses regularly posts articles on facebook related to this topic. Since he's got a relevant science background I trust that he's able to tell what is legitimate research and not posting fluff that is just magical thinking. This is the latest article he posted.

Although it doesn’t provide a conclusive answer, a study published yesterday (May 14) in Cell appears to be good news on the immunity front. Researchers at the La Jolla Institute for Immunology in California took blood from 20 adults who’d recovered from COVID-19 and exposed the samples to proteins from the SARS-CoV-2 virus. All of the patients had CD4+ helper T cells that recognized the virus’s spike protein, and 70 percent of them had CD8+ killer T cells that responded to the same protein. “Our data show that the virus induces what you would expect from a typical, successful antiviral response,” says coauthor Shane Crotty in an institute press release.

I'm still going to practice social distancing and other steps to try and prevent getting infected because, as others have pointed out, we just don't know the long-term effects of this virus. If possible I'd rather not learn the hard way that Covid causes damage to the body over time, or that it lies dormant for a period of time and then lashes out as a completely different illness the way the chickenpox virus does.
