Not COULD become obsolete, most likely WILL become obsolete....

Not COULD become obsolete, most likely WILL become obsolete. Anybody who understands this technology will be viewing 2 possibilities:

1. WBT with their knowledge are well positioned to stay one step ahead of their potential competitors and remain leaders in the field. Look at Apple - did they say we are World beaters and think their Apple 2+ computer technology in the 1980s was going to still be current in 2022?

2. In the case of another company developing disruptive technology then those who understand the technology would get on board early and transition their holding accordingly.

Of course WBT has NOT reached the final frontier in this field but my feeling is that the WBT team are capable of leading the pack. In a long race there are often lead changes. If you don't understand the technology that you have invested in, then you run the risk on getting your fingers burnt.

Just saying - and definitely not advice, just my personal take.
