Why be involved with tech that's in the winter of it's lifespan? It's academic to these people and why they are easily attracting the top talent in the industry-from sales reps to engineers to mgmt, quality control etc. Next gen technology means just that,it took almost ten years to get rid of current useless screening protocol, Imsc is going to be the gold standard for ETD/Drug screening for the next decade. Just imagine what new tech they come up with in the future, and how streamlined the process will be after they have penetrated the TSA gauntlet. Bottom line here is we are still sub floor to 99.9% of the investing world. The biggest challenge they will have going fwd is the ability to keep up with demand- not the worst problem to have IMO.
