"Months of intense research" have yielded at least 200+ compounds being tested for various activities. Large consortia have formed. A lot of things are being done in parallel to speed up testing (see vaccine research).
It takes time to prove efficacy: remedisivir only showed its efficacy in a 800+ people cohort. At first the time to administration was not correct: lopinavir-ritonavir were thought to be not working, but perhaps they do if given earlier in treatment, and what not.
I don't know what the author's expectations are, but we're witnessing a very fast pace of drug development and testing (not without warts, of course). What did the author expect, a miracle cure in 6 months? Most of the drugs being tested at this point are repurposed: the new ones will be tested through the summer and early autumn.
And there are wins like with dexamethasone, which is effective and cuts down mortality.
I recommend (to the author) a thorough reading of what's going on before launching in such a pessimistic piece. Yes, we might still be in hot waters. No, it's not that we will be destroyed by this coronavirus.
By the way, indications from early data from vaccine development tells us that it immunity is generated. The open questions are the duration, and the efficacy in a diverse population. But that's what trials are for. The fastest vaccine ever made took 4 years, IIRC. We're close to having results in 8 months (positive or not, the data will tell).
P.S.: The cold is mainly caused by rhinoviruses. Coronaviruses only account for a small percentage of that.
