I recently bought gluten-free bubble bath. Didn’t realize people were eating the stuff.

Surely you've seen skin-based allergy tests. Allergies don't just affect the digestive system.

I wouldn’t put Blockchain in the past tense here. Having recently conducted a job search in IT, the number of jobs, companies, and startups that are either completely focused on, or at least discussing blockchain is staggering. It’s in the same boat with IoT. With some job descriptions you get both! I can’t roll my eyes hard enough.

At least IoT seems to have settled a bit so that the things that are still around are often actually pretty useful. I just wish vendors would stop trying to get nontechnical customers to base business-critical systems around cloud-based services. No, your feed bin level should NOT have to get to your dashboard 1km away via a 4G connection, a SIM not under your control, and a vendor's cloud service. Install some fiber or a wireless bridge with a couple of cantennas and then if some goober dredges up an undersea cable or you forget to update your credit card and your subscription fee bounces all your cows don't all die.

Classic hype cycle. We've seen mRNA can do one thing really well, now it will be suggested to do everything. It will be a few years before we have a clear picture.

That seems unlikely to me. mRNA could be vaguely defined as a biological programming language. I don't think people like thinking about it so its poor marketing too.

unlike other fads though this works. TBH i don't think it s going to be limited to RNA, DNA is already a major target especially after CRISPR.

It's been 6 years since the CRISPR breakthroughs , how are we doing on that front?

My money's on mRNAI/ML.
