Intel MacBook supplies are decreasing which has actually caused them to go up in price. In a few years they will be difficult to get. Any company which uses MacBooks is going to have to make the switch at some point - better sooner than later.

When I first joined my current employer late November/early December (employee 1 with an M1), we could not source Intel directly from Apple. The only option was to purchase a refurbished device.
If you aren't ready to switch to ARM, consider Linux.

Yes. Exactly. It tells us that had the OP jumped all in to Apple Silicon since the day it launched, then they would have been waiting months to do their work. Little of the software from Intel was actually working in November 2020.
Thus, the sensible and smart action to do was wait and stick to Intel. By the time the software ecosystem caught up to Apple Silicon, the M2 Macbooks were announced meaning that they can upgrade directly to M2, skipping the M1 altogether with more working software than on release day.
