Time is money, and the larger your team is the more that the costs of learning a new tech are amplified.
Using his off-the-cuff, totally subjective "a few days" estimate, and assigning 'few' at a conservative 2 days, that would mean my team would spend roughly 50 days doing nothing but learning this one very specific technology. That's 50 days of not producing revenue or otherwise addressing client concerns.
Now, I'm not saying that we shouldn't be able to take time to do things like this (learn and embed new tech), but to dismissively say "a few days" like it's trivial is severely underestimating the impact of dropping everything during that time to do nothing but learn about a tech that will most likely be obsolete or superseded in only a few years time.
