I would argue against all of 1, 2 and 3.
1. Anything AI/ML-based that can be applied to COVID-19 will be. 90% will be useless, but some percentage will pivot to these applications as their new business model. There may be some others that see cutbacks, but most companies should get a boost from the good PR of the ones that work.
2. I've seen a couple different sources pointing to blockchain as a good solution to inventory management and tracing, both seemingly important given current events. Second wave infections will keep this at the forefront through the next few years at least.
3. Subscription boxes for foodstuffs (meal kits specifically) probably saw a HUGE boost when a few million people suddenly had a lot of free time, coupled with supply chain problems and shopping difficulty. Other periodic vendors may benefit as well if shopping remains inconvenient, and customers may get used to the convenience and stick with them after everything goes back to normal.
