I worked for a company where we built a prototype for a rewrite of their flagship product in VB. Meanwhile a big team of programmers implemented the “production” version in VC++. But at that time a bunch of the controls available in VB were not in VC, so they lagged quite a bit. Of course management saw the prototype working (it was a CRUD app for property management) and said why not just use this. The C++ programmers turned up their noses at working in VB and were summarily fired, leaving me and a team of contractors to finish the job. 100% the right business decision and a good lesson on getting too precious with your tech.
